From 761685818c544b237058611d91be524772066073 Mon Sep 17 00:00:00 2001 From: Julien Goux Date: Fri, 12 Jun 2026 12:45:27 +0200 Subject: [PATCH 001/183] docs: add target architecture roadmap for pg-delta and pg-topo Records the outcome of a full architecture review of the two core packages: verified findings (extraction snapshot consistency bug, JSON.stringify equality cost, sort-layer scaling, objects/ boilerplate volume, WASM dependency tax), the decisions taken (moderate packaging, shadow-DB declarative convergence), what explicitly stays, and a 7-phase incremental roadmap. Docs-only change: no package behavior change, no changeset.

Every code claim carries a +`path:line` citation verified against the baseline commit. It is a decision +record, not a menu: each topic ends in one recommendation; rejected +alternatives get one line. + +--- + +## 1. Executive summary + +pg-delta's pipeline is correct and well-layered. Extraction, diffing, +dependency expansion, normalization, sorting, serialization, and apply are +cleanly separated; dependency edges come from `pg_depend` (authoritative) +rather than SQL re-parsing; the sort layer's cycle-handling doctrine +(`packages/pg-delta/CLAUDE.md`) is hard-won and right. None of that changes. + +The review found four problems, in decreasing severity: + +1. **A latent correctness bug**: catalog extraction runs ~28 queries on + different pool connections with no shared snapshot, so the catalog and its + `pg_depend` edges can be mutually inconsistent under concurrent DDL + (§3.1). +2. **Built for hundreds of objects, not 10k+**: object equality is a double + `JSON.stringify` per pair per diff (§3.2); the sort layer scans the entire + catalog's dependency rows regardless of diff size and rebuilds its graph + from scratch on every cycle-break round (§3.3); the topological queue is + O(V²) (§3.3). +3. **~40% of the code is mechanical boilerplate**: `src/core/objects/` is 256 + source files / 31,162 LOC (plus 127 test files / 18,505 LOC) across 21 + object-type directories and 106 change classes, of which roughly 65% are + structurally identical (§4). +4. **Library consumers pay for the CLI and a WASM parser**: `@supabase/pg-topo` + (→ libpg-query WASM), `@stricli/core`, and `chalk` are hard `dependencies` + of the library even for pure `createPlan` users + ([package.json:80-89](../packages/pg-delta/package.json)) (§5). + +The target architecture keeps the pipeline shape and every public contract +that matters (stable-ID wire format, plan fingerprints, the +`creates/drops/requires/invalidates` + `serialize()` change contract) and +changes how the stages are implemented: + +| Track | Change | Headline outcome | +|---|---|---| +| Correctness & perf (§3) | Snapshot-consistent parallel extraction; content-hash equality; single-build sort with depend pre-filtering | Consistency bug fixed; diff 5–20× faster; tiny-diff-vs-huge-catalog goes from O(catalog) to ~O(changes) | +| Simplicity (§4) | Typed stable IDs; one generic `Change` family; `ObjectTypeSpec` registry + one generic diff engine | −11–12K source LOC, ~150 fewer files; new object types become ~1 spec file | +| API & packaging (§5) | Layered subpath exports; pg-topo becomes optional (dynamic import) | WASM-free core install; `diffCatalogs`/`sortChanges` independently usable | +| Test & CI velocity (§6) | Template databases; catalog-fixture unit diffs replacing most Docker tests | 2–5× wall-clock; the 45-job integration matrix shrinks structurally | +| Declarative (§7) | Converge on shadow-DB diff; round-based apply becomes the fallback | One trusted ordering engine (`pg_depend`); pg-topo narrows to dev-time ordering/validation | + +Decisions already taken (with maintainer sign-off): roadmap-first delivery; +**moderate** packaging (no new packages — the five-package split and a shared +`pg-graph` kernel were evaluated and rejected, §5.3); **shadow-DB +convergence** for declarative apply (§7). + +--- + +## 2. What stays (explicitly) + +A review that only lists changes invites accidental regressions of good +decisions. The following are load-bearing and deliberately **unchanged**: + +- **The seven-stage pipeline shape**: extract → diff → expand-replace → + normalize → sort → serialize → apply, and the change contract — every + change exposes `creates` / `drops` / `requires` / `invalidates` (stable-ID + string arrays) plus `serialize(options?)` + ([base.change.ts](../packages/pg-delta/src/core/objects/base.change.ts)). + The sort/plan/apply layers already consume *only* this contract; that is + precisely what makes the simplicity track (§4) low-risk. +- **The sort module's architecture.** Two-phase ordering (drops in reverse + topological order, then creates/alters forward), a generic graph builder, + weak-edge filtering, and cycle-breaking by change injection. The decision + tree for *where* cycle handling lives (object-local diff vs post-diff + normalization vs sort-phase injection vs `invalidates`) documented in + `packages/pg-delta/CLAUDE.md` stays canonical. §3.4 tunes data structures + inside this design; it does not redesign it. +- **`pg_depend` at extract time as the only dependency source** for the core + diff path. No SQL parser ever enters the diffing path. This constraint has + repeatedly proven itself (expression-level dependencies that parsers miss, + Postgres-version drift) and is the foundation of §7's recommendation. +- **Zod model schemas and per-type extractor SQL** in `.model.ts`. They + encode real per-version `pg_catalog` knowledge. The registry (§4.3) + references extractors; it does not replace them. +- **Bespoke diff/serialize for the genuinely complex types** — table + (3,528 LOC including a 975-line `table.alter.ts` with ~25 ALTER variants), + procedure (signature-keyed identity), view/materialized-view + (replace-vs-alter, dependency reconstruction). These are escape hatches in + the registry, never templated. +- **Full in-memory catalog materialization.** At 10k objects the catalog is + tens of MB — trivial. Streaming/lazy diffing would forfeit cross-type + dependency resolution and fingerprinting for no measurable win below ~100k + objects. Explicitly rejected as premature. +- **Sequential single-transaction apply** + ([apply.ts:125-131](../packages/pg-delta/src/core/plan/apply.ts)). Parallel + DDL apply is rejected: DDL takes `ACCESS EXCLUSIVE` locks, would deadlock on + shared catalogs, and would break the transaction as the atomicity boundary. + The topological order exists exactly so that serial execution is safe. +- **The pg-delta / pg-topo identity duplication is deliberate.** pg-delta's + stable IDs (`table:public.users`) are a *catalog-exact wire format*, + persisted in plan fingerprints and matched against `pg_depend`-derived rows. + pg-topo's `ObjectRef` is a *lexical-approximate* identity recovered from + parsed SQL (quoted-identifier normalization, signature inference, + builtin-type filtering). The packages also differ in cycle policy: pg-delta + rewrites cycles (change injection); pg-topo reports them (diagnostics). + Unifying these would force the exact world to carry the approximate world's + fuzzy-matching semantics. Future contributors should not "DRY" them + together. + +--- + +## 3. Correctness & performance track + +### 3.1 Snapshot-consistent parallel extraction + +**Problem.** `extractCatalog` fires ~28 extractors via `Promise.all` over a +`pg.Pool` +([catalog.model.ts:352-381](../packages/pg-delta/src/core/catalog.model.ts)) +whose default size is 5 +([postgres-config.ts:108](../packages/pg-delta/src/core/postgres-config.ts)). +Each query lands on whatever connection frees up, at a different wall-clock +time, with no shared transaction. Consequences: + +- **Correctness**: the object queries and the `pg_depend` query + ([depend.ts:511](../packages/pg-delta/src/core/depend.ts)) can observe + different database states under concurrent DDL. The result is a catalog + whose dependency rows reference objects the catalog doesn't contain (or + vice versa). The `unknown:` filter in + [graph-builder.ts:26-33](../packages/pg-delta/src/core/sort/graph-builder.ts) + silently drops such edges — masking the symptom, losing real ordering + information. +- **Latency**: 28+ queries contending for 5 connections ≈ six serial waves, + and each of the heavy queries (`pg_get_*def`, `aclexplode`, lateral joins) + pays planning and queueing overhead. `applyPlan` runs **three full + extractions** per apply: source + target up front + ([apply.ts:83-86](../packages/pg-delta/src/core/plan/apply.ts)) and a + post-apply verification extract + ([apply.ts:138-152](../packages/pg-delta/src/core/plan/apply.ts)). + +**Target.** The pg_dump-parallel model — one exported snapshot, N workers: + +```ts +// catalog.model.ts (sketch) +const lead = await pool.connect(); +await lead.query("BEGIN ISOLATION LEVEL REPEATABLE READ READ ONLY"); +const { rows: [{ snap }] } = await lead.query("SELECT pg_export_snapshot() AS snap"); + +const runExtractor = async (extract: (c: ClientLike) => Promise) => { + const worker = await pool.connect(); + await worker.query("BEGIN ISOLATION LEVEL REPEATABLE READ READ ONLY"); + await worker.query(`SET TRANSACTION SNAPSHOT '${snap}'`); + try { return await extract(worker); } + finally { await worker.query("COMMIT"); worker.release(); } +}; +// run all extractors (objects + depends + version + user) with bounded +// concurrency over the same snapshot, then COMMIT + release the lead. +``` + +Every extractor sees the exact same database state; parallelism is preserved +(and improves, since the pool default rises to match the worker count). This +is days of work and fixes the bug outright. + +**Second step, only if profiling justifies it**: collapse the per-type queries +into ~6 "object family" queries returning `jsonb_agg` rows (relations, +routines, types, security, replication, misc), cutting round-trips ~5×. A +single mega-query is rejected — planner-hostile and unmaintainable. + +**Also**: make the post-apply verification extract **opt-in** instead of +opt-out (today it runs unless `verifyPostApply: false`, +[apply.ts:138](../packages/pg-delta/src/core/plan/apply.ts)). The plan's +fingerprint contract already guards pre-apply state; the third extraction is a +paranoia check that belongs in CI, not in every production apply. One-third +fewer extractions per apply. + +### 3.2 Content-hash equality + +**Problem.** `BasePgModel.equals` +([base.model.ts:70-75](../packages/pg-delta/src/core/objects/base.model.ts)) +delegates to `deepEqual`, which is +`stringifyWithBigInt(a) === stringifyWithBigInt(b)` +([objects/utils.ts:36-37](../packages/pg-delta/src/core/objects/utils.ts)) — +a full recursive `JSON.stringify` of both sides, recomputed for every shared +object on every diff. For a table model (columns, constraints, privileges, +security labels) that is a deep tree. At 10k shared objects, this dominates +diff CPU. `table.diff.ts` already works around it locally with +cheap-scalar-first comparisons — evidence the cost is real. + +**Target.** A memoized content hash on the base model: + +```ts +// base.model.ts (sketch) +abstract class BasePgModel { + #contentHash?: string; + get contentHash(): string { + return (this.#contentHash ??= hashCanonical(this.stableSnapshot().data)); + } + equals(other: BasePgModel): boolean { + return this.stableId === other.stableId + && this.contentHash === other.contentHash; + } +} +``` + +`hashCanonical` = canonical serialization (sorted keys, bigint-safe — the +existing `stringifyWithBigInt` semantics) fed to a fast non-cryptographic hash +(xxhash64 or FNV-1a). The hash is computed once per object, lazily, and +overlaps with extraction I/O wait. `stableSnapshot()` is already the correct +equality surface — subclasses override it to drop unstable fields (the +"physical attnums vs logical names" rule), so the hash inherits every +normalization for free. + +Two integration points: + +- `fingerprint.ts` already canonically stringifies models for plan + fingerprints; feed it the same canonical string so the work is shared (keep + SHA-256 there — fingerprints cross machine boundaries). +- Keep `table.diff.ts`'s scalar fast paths: they classify *what kind* of + ALTER to emit for objects already known to differ. The hash replaces only + the *are-they-equal* gate. + +Diff becomes O(n) 8-byte compares. Expected 5–20× on the diff stage at scale. + +### 3.3 Sort: build once, scan only what changed + +**Problems** (all in `src/core/sort/`): + +1. `convertCatalogDependenciesToConstraints` iterates **every** `pg_depend` + row in the catalog on every sort + ([graph-builder.ts:26](../packages/pg-delta/src/core/sort/graph-builder.ts)), + regardless of how many changes are being sorted. A one-change diff against + a 10k-object catalog (≈100k+ depend rows) pays the full scan — twice, once + per phase. +2. `sortPhaseChanges` re-invokes `attemptSortRound` from scratch after every + cycle-breaking change injection + ([sort-changes.ts:259-289](../packages/pg-delta/src/core/sort/sort-changes.ts)), + and `attemptSortRound` rebuilds all graph data each call + ([sort-changes.ts:161-167](../packages/pg-delta/src/core/sort/sort-changes.ts)). +3. `performStableTopologicalSort` keeps its ready-queue sorted with linear + scan + `splice`, and pops with `shift` + ([topological-sort.ts:33-52](../packages/pg-delta/src/core/sort/topological-sort.ts)) + — O(V²) exactly in the large-schema case where thousands of independent + nodes are ready simultaneously. +4. `logicalSort`'s comparator re-runs regexes per comparison + ([logical-sort.ts:71-73](../packages/pg-delta/src/core/sort/logical-sort.ts)). + +**Target**, in order of impact: + +1. **Pre-filter depend rows to the change set.** Index the phase's + created/required stable IDs first, then visit only depend rows whose + endpoints appear in that index. Sorting cost becomes O(changes · + avg-fanout) instead of O(catalog). This is the single biggest sort win and + makes the common dev-loop case (tiny diff, huge database) effectively + O(changes). +2. **Build the graph once per phase; patch on injection.** Cycle injection + adds a handful of changes — extend the adjacency/index structures + incrementally instead of rebuilding. Re-running `findCycle` after each + repair is fine (cycles are rare); rebuilding everything is not. +3. **Binary min-heap ready-queue** keyed by original index → O(E log V), + identical output order (the tie-break rule is unchanged). +4. **Parse stable IDs once** into structs before `logicalSort`'s comparator + runs (this falls out of typed stable IDs, §4.1). + +The phase structure, edge semantics, weak-edge filters, and cycle-breaker +logic are untouched; the existing sort test suite is the oracle. + +**Expected multipliers** (estimates, to be validated with a benchmark fixture +at ~10k objects): extraction 2–4×, diff 5–20×, sort 3–10× — compounding, +since they are different pipeline stages. + +--- + +## 4. Simplicity track + +### 4.0 Where the volume is + +`src/core/objects/` = **256 source files / 31,162 LOC** + **127 test files / +18,505 LOC**, across 21 object-type directories (some hold multiple kinds: +`type/` → enum/composite/range; `foreign-data-wrapper/` → FDW, server, +foreign table, user mapping). Each type follows the same template — +`.model.ts`, `.diff.ts`, and a `changes/` directory with +create/alter/drop/comment/privilege/security-label classes — for **106 +concrete change classes** total. + +The decisive finding: **everything downstream of diffing is already +generic.** The sort, plan, and apply layers consume only +`creates/drops/requires/invalidates` + `serialize()`. The 106 classes exist +to produce four string arrays and one SQL string each. Per-type *information* +varies; per-type *structure* almost never does. Roughly 65% of the volume is +structural duplication, concentrated in the ~15 cookie-cutter types +(collation 676 LOC, extension 646, language 758, schema 792 … up to +publication 1,116), while table (3,528), procedure (1,608), role (1,815), and +the view family carry genuinely irreducible logic. + +The duplication also leaks outward as five hand-maintained per-`objectType` +dispatch sites that must be edited for every new type: + +- `getPrivilegeTargetStableId` + ([catalog.diff.ts:47](../packages/pg-delta/src/core/catalog.diff.ts)) +- `getSchema` + ([change-utils.ts:10](../packages/pg-delta/src/core/change-utils.ts)) +- `getPrimaryStableId` + ([fingerprint.ts:88](../packages/pg-delta/src/core/fingerprint.ts)) +- `OBJECT_TYPE_TO_PROPERTY_KEY` + ([change.types.ts:65](../packages/pg-delta/src/core/change.types.ts), used + by `integrations/filter/flatten.ts`) +- `getFilePath` + ([export/file-mapper.ts:59](../packages/pg-delta/src/core/export/file-mapper.ts)) + +### 4.1 Typed stable IDs (first — it unblocks everything) + +Stable IDs are strings built by `stableId.*` helpers but **re-parsed** with +regex/string slicing where structure is needed — e.g. +`stableId.slice("procedure:".length, paren)` and `normalizeDependentId` in +[expand-replace-dependencies.ts:419-425](../packages/pg-delta/src/core/expand-replace-dependencies.ts). +That is fragile (quoting, signature commas) and scatters the format. + +**Target**: one parsed value type with a frozen canonical string form. + +```ts +// src/core/stable-id.ts (sketch) +export type StableId = + | { kind: "schema"; schema: string } + | { kind: "table" | "view" | "materializedView" | "sequence" | "domain" + | "collation" | "type" | "foreignTable"; schema: string; name: string } + | { kind: "procedure"; schema: string; name: string; args: string[] } + | { kind: "column" | "constraint" | "index"; schema: string; table: string; name: string } + | { kind: "role"; role: string } + | { kind: "comment" | "acl" | "securityLabel"; target: StableId; /* … */ } + | { kind: "membership"; role: string; member: string } + // … defacl, server, userMapping, foreignDataWrapper, … + +export function formatStableId(id: StableId): string; // byte-identical to today's strings +export function parseStableId(s: string): StableId; +``` + +**The wire format is frozen.** Stable-ID strings are persisted in plan +fingerprints and matched against SQL-side string synthesis in `depend.ts`; +`formatStableId` must reproduce today's output byte-for-byte, verified by a +parse/format round-trip test over every existing helper. Graph keys and the +change contract keep using strings; structure is recovered with +`parseStableId` instead of regex. + +### 4.2 One generic `Change` family with a typed `ref` + +Today every change class carries its model under a per-type property +(`.table`, `.collation`, …), which is what forces the five dispatch switches +and the 21-member union in +[change.types.ts](../packages/pg-delta/src/core/change.types.ts). + +**Target**: the base change exposes one uniform reference — + +```ts +interface ObjectRef { + objectType: ObjectType; + stableId: StableId; + model: BasePgModel; +} + +abstract class Change { + abstract operation: "create" | "alter" | "drop"; + abstract scope: "object" | "comment" | "privilege" | "security_label" | "membership" | "default_privilege"; + abstract ref: ObjectRef; + abstract creates: string[]; abstract drops: string[]; + abstract requires: string[]; get invalidates(): string[] { return []; } + abstract serialize(options?: SerializeOptions): string; +} +``` + +— plus a small set of generic concrete shapes (`GenericCreate`, +`GenericDrop`, `GenericAlter` with a discriminated `action` payload, +`SetComment`, `GrantPrivilege` / `RevokePrivilege` / `RevokeGrantOption`, +`SetSecurityLabel`) whose behavior is driven by the registry (§4.3). Complex +types keep their bespoke classes (`AlterTableAlterColumnType` et al.) but +extend the same base and expose the same `ref`. + +With `ref` in place, all five switches collapse to one-liners +(`change.ref.stableId`, `change.ref.model.schemaName`, a registry lookup for +file paths) and `OBJECT_TYPE_TO_PROPERTY_KEY` is deleted. The filter DSL's +public `/` paths are preserved by flattening `ref.model` +under the same keys — guarded by a key-set equality test (§9). + +### 4.3 `ObjectTypeSpec` registry + one generic diff engine + +```ts +// src/core/registry/spec.ts (sketch) +interface ObjectTypeSpec { + objectType: ObjectType; + sqlKeyword: string; // "COLLATION", "TABLE", … + hasComment: boolean; + hasPrivileges: boolean; // + columnLevelPrivileges for relations + hasSecurityLabel: boolean; + extract(pool: Pool): Promise; // existing extractor, referenced not rewritten + requires(model: M): StableId[]; // schema, owner, types, collations, … + identitySql(model: M): string; // "schema.name" / "schema.name(args)" + serializeCreate(model: M, opts?: SerializeOptions): string; + alterableFields?: Record string>; + customDiff?(ctx: DiffContext, main: Record, branch: Record): Change[]; +} +``` + +One generic engine consumes the spec: set-algebra created/dropped/altered +(via §3.2 hashes), then emits `GenericCreate` (+ owner alter, comments, +grants, security labels), `GenericDrop`, and per-field `GenericAlter` — +falling back to drop+create for non-alterable fields. It reuses the existing +shared helpers (`emitObjectPrivilegeChanges` — already used by 16 of 21 +types — and `diffSecurityLabels` — 18 of 21); the registry deletes the +per-type *class wrappers* around them, not the logic. `diffCatalogs`'s 21 +hand-sequenced imports become a loop over the registry. + +**Scope boundary**: the ~15 cookie-cutter types go fully generic. Table, +procedure, view, materialized-view, role, and subscription keep their +diff/serialize behind `customDiff` and only adopt the generic +comment/privilege/security-label shapes. Quirky-but-simple cases (collation's +`REFRESH VERSION`) are an `alterableFields` entry, not a reason to fork. + +**Quantified estimate**: −11–12K source LOC and ~150 fewer files (≈35–40% of +`objects/`), with a comparable test-LOC reduction after per-class test files +collapse into per-spec tests. Adding a future object type drops from ~13 +files to ~2 (model + spec). + +### 4.4 `depend.ts` decomposition + +[depend.ts](../packages/pg-delta/src/core/depend.ts) is 1,895 lines but only +two functions: `extractPrivilegeAndMembershipDepends` (line 43 — a series of +independent `aclexplode`/membership/defacl sub-queries) and `extractDepends` +(line 511 — the core `pg_depend` synthesis query with 30+ CTEs). + +**Target**: split the ACL/membership part into ~5 named functions +(`relationAclDepends`, `schemaAclDepends`, `membershipDepends`, +`defaclDepends`, `fdwAclDepends`) run via `Promise.all` — they are already +independent queries. **Keep the core `pg_depend` query whole**: it is one +recursive join over `pg_depend`; splitting it would multiply round-trips and +re-implement the OID→stable-ID mapping N times. Centralize the SQL-side +stable-ID `format(...)` literals into one CTE that mirrors `formatStableId`, +so the wire format lives in exactly two audited places (TS + SQL). + +Moving per-type dependency extraction next to each type's extractor was +evaluated and rejected: dependency synthesis is inherently cross-type. + +### 4.5 Explicit plan pipeline + +`diffCatalogs` currently interleaves raw diffing with an inline +dropped-target ACL filter, then callers wire `expandReplaceDependencies` and +`normalizePostDiffChanges` around it. **Target**: a named stage list with one +contract — + +```ts +const STAGES: Array<(changes: Change[], ctx: PlanContext) => Change[]> = [ + rawDiff, filterDroppedObjectAcls, expandReplaceDependencies, normalizePostDiffChanges, +]; +``` + +This is a wiring change only. The CLAUDE.md doctrine that these stages are +distinct *by the information they need* is preserved — the goal is to make +the chokepoints legible and independently testable, not to merge them. + +### 4.6 Migration order (each step independently shippable) + +Old and new coexist throughout because everything downstream speaks the same +change contract; the registry dispatches per-type to either the spec engine +or the legacy diff function during transition. + +1. Typed stable IDs (`stable-id.ts`), helpers reimplemented on top; replace + the parsers in `expand-replace-dependencies.ts`. Zero wire-format drift, + proven by round-trip tests. +2. Add `ref` to the base change (temporary adapter derives it from existing + per-type properties); collapse the five switches; delete + `OBJECT_TYPE_TO_PROPERTY_KEY`. +3. Registry + generic engine; migrate **collation**, then **extension** as + proofs. Each migration deletes a `changes/` directory and a `*.diff.ts`. +4. Batch-migrate the remaining cookie-cutter types, one PR per batch. +5. Complex types last: route through the registry via `customDiff`; swap + their comment/privilege/seclabel wrappers for the generic shapes; bespoke + alter classes stay. +6. Delete the legacy union and dead base plumbing. + +**Hard rule per PR: zero serialized-SQL drift.** The existing per-type diff +tests and the integration roundtrip suite are the oracle; a migration PR that +changes any emitted SQL byte is wrong by definition. + +--- + +## 5. API & packaging track (moderate) + +### 5.1 Layered subpath exports + +The current root export is a flat bag mixing catalog, plan, execution, and +integration concerns, while the two most reusable functions — +`diffCatalogs` and `sortChanges` — are internal. Embedders (e.g. the +Supabase CLI) that already hold two catalogs must go through the monolithic +`createPlan`. + +**Target** `@supabase/pg-delta` exports: + +```text +. createPlan / applyPlan / extractCatalog (facade — unchanged) +./catalog extractCatalog, serializeCatalog, deserializeCatalog, snapshots +./diff diffCatalogs(main, branch) -> Change[] +./sort sortChanges(ctx, changes) -> Change[] +./plan createPlan, applyPlan, Plan, fingerprints, sql-format +./integrations filter + serialize DSL (vendor-neutral) — supabase stays at + ./integrations/supabase +./catalog-export (existing, unchanged) +``` + +Each layer is independently usable; the facade stays the documented happy +path.

Extraction, diffing, -dependency expansion, normalization, sorting, serialization, and apply are -cleanly separated; dependency edges come from `pg_depend` (authoritative) -rather than SQL re-parsing; the sort layer's cycle-handling doctrine -(`packages/pg-delta/CLAUDE.md`) is hard-won and right. None of that changes. - -The review found four problems, in decreasing severity: - -1. **A latent correctness bug**: catalog extraction runs ~28 queries on - different pool connections with no shared snapshot, so the catalog and its - `pg_depend` edges can be mutually inconsistent under concurrent DDL - (§3.1). -2. **Built for hundreds of objects, not 10k+**: object equality is a double - `JSON.stringify` per pair per diff (§3.2); the sort layer scans the entire - catalog's dependency rows regardless of diff size and rebuilds its graph - from scratch on every cycle-break round (§3.3); the topological queue is - O(V²) (§3.3). -3. **~40% of the code is mechanical boilerplate**: `src/core/objects/` is 256 - source files / 31,162 LOC (plus 127 test files / 18,505 LOC) across 21 - object-type directories and 106 change classes, of which roughly 65% are - structurally identical (§4). -4. **Library consumers pay for the CLI and a WASM parser**: `@supabase/pg-topo` - (→ libpg-query WASM), `@stricli/core`, and `chalk` are hard `dependencies` - of the library even for pure `createPlan` users - ([package.json:80-89](../packages/pg-delta/package.json)) (§5). - -The target architecture keeps the pipeline shape and every public contract -that matters (stable-ID wire format, plan fingerprints, the -`creates/drops/requires/invalidates` + `serialize()` change contract) and -changes how the stages are implemented: - -| Track | Change | Headline outcome | -|---|---|---| -| Correctness & perf (§3) | Snapshot-consistent parallel extraction; content-hash equality; single-build sort with depend pre-filtering | Consistency bug fixed; diff 5–20× faster; tiny-diff-vs-huge-catalog goes from O(catalog) to ~O(changes) | -| Simplicity (§4) | Typed stable IDs; one generic `Change` family; `ObjectTypeSpec` registry + one generic diff engine | −11–12K source LOC, ~150 fewer files; new object types become ~1 spec file | -| API & packaging (§5) | Layered subpath exports; pg-topo becomes optional (dynamic import) | WASM-free core install; `diffCatalogs`/`sortChanges` independently usable | -| Test & CI velocity (§6) | Template databases; catalog-fixture unit diffs replacing most Docker tests | 2–5× wall-clock; the 45-job integration matrix shrinks structurally | -| Declarative (§7) | Converge on shadow-DB diff; round-based apply becomes the fallback | One trusted ordering engine (`pg_depend`); pg-topo narrows to dev-time ordering/validation | - -Decisions already taken (with maintainer sign-off): roadmap-first delivery; -**moderate** packaging (no new packages — the five-package split and a shared -`pg-graph` kernel were evaluated and rejected, §5.3); **shadow-DB -convergence** for declarative apply (§7). +## 1. The problem, stated purely ---- +Given two PostgreSQL schema states — each obtainable from a live database, +from SQL files, or from a serialized snapshot — produce a **minimal, +correctly ordered, reviewable, safety-classified** DDL script that transforms +one state into the other, **deterministically**, and be able to **prove** it +did. + +Five sub-problems follow from this statement, and any architecture in this +space must answer all five: state capture, comparison, action synthesis, +ordering, execution. Every serious tool (pg_dump/pg_restore itself, migra, +pg-schema-diff, atlas, skeema) converges on this staged shape; the +architectural freedom — and where this design differs from the current +codebase — is *within* the stages: where semantic knowledge lives, who is +trusted to elaborate PostgreSQL semantics, how cycles are handled, and how +correctness is established. -## 2. What stays (explicitly) - -A review that only lists changes invites accidental regressions of good -decisions. The following are load-bearing and deliberately **unchanged**: - -- **The seven-stage pipeline shape**: extract → diff → expand-replace → - normalize → sort → serialize → apply, and the change contract — every - change exposes `creates` / `drops` / `requires` / `invalidates` (stable-ID - string arrays) plus `serialize(options?)` - ([base.change.ts](../packages/pg-delta/src/core/objects/base.change.ts)). - The sort/plan/apply layers already consume *only* this contract; that is - precisely what makes the simplicity track (§4) low-risk. -- **The sort module's architecture.** Two-phase ordering (drops in reverse - topological order, then creates/alters forward), a generic graph builder, - weak-edge filtering, and cycle-breaking by change injection. The decision - tree for *where* cycle handling lives (object-local diff vs post-diff - normalization vs sort-phase injection vs `invalidates`) documented in - `packages/pg-delta/CLAUDE.md` stays canonical. §3.4 tunes data structures - inside this design; it does not redesign it. -- **`pg_depend` at extract time as the only dependency source** for the core - diff path. No SQL parser ever enters the diffing path. This constraint has - repeatedly proven itself (expression-level dependencies that parsers miss, - Postgres-version drift) and is the foundation of §7's recommendation. -- **Zod model schemas and per-type extractor SQL** in `.model.ts`. They - encode real per-version `pg_catalog` knowledge. The registry (§4.3) - references extractors; it does not replace them. -- **Bespoke diff/serialize for the genuinely complex types** — table - (3,528 LOC including a 975-line `table.alter.ts` with ~25 ALTER variants), - procedure (signature-keyed identity), view/materialized-view - (replace-vs-alter, dependency reconstruction). These are escape hatches in - the registry, never templated. -- **Full in-memory catalog materialization.** At 10k objects the catalog is - tens of MB — trivial. Streaming/lazy diffing would forfeit cross-type - dependency resolution and fingerprinting for no measurable win below ~100k - objects. Explicitly rejected as premature. -- **Sequential single-transaction apply** - ([apply.ts:125-131](../packages/pg-delta/src/core/plan/apply.ts)). Parallel - DDL apply is rejected: DDL takes `ACCESS EXCLUSIVE` locks, would deadlock on - shared catalogs, and would break the transaction as the atomicity boundary. - The topological order exists exactly so that serial execution is safe. -- **The pg-delta / pg-topo identity duplication is deliberate.** pg-delta's - stable IDs (`table:public.users`) are a *catalog-exact wire format*, - persisted in plan fingerprints and matched against `pg_depend`-derived rows. - pg-topo's `ObjectRef` is a *lexical-approximate* identity recovered from - parsed SQL (quoted-identifier normalization, signature inference, - builtin-type filtering). The packages also differ in cycle policy: pg-delta - rewrites cycles (change injection); pg-topo reports them (diagnostics). - Unifying these would force the exact world to carry the approximate world's - fuzzy-matching semantics. Future contributors should not "DRY" them - together. +Out of scope, permanently: data migrations (DML). The tool's contract is +schema state, not data movement. --- -## 3. Correctness & performance track - -### 3.1 Snapshot-consistent parallel extraction - -**Problem.** `extractCatalog` fires ~28 extractors via `Promise.all` over a -`pg.Pool` -([catalog.model.ts:352-381](../packages/pg-delta/src/core/catalog.model.ts)) -whose default size is 5 -([postgres-config.ts:108](../packages/pg-delta/src/core/postgres-config.ts)). -Each query lands on whatever connection frees up, at a different wall-clock -time, with no shared transaction. Consequences: - -- **Correctness**: the object queries and the `pg_depend` query - ([depend.ts:511](../packages/pg-delta/src/core/depend.ts)) can observe - different database states under concurrent DDL. The result is a catalog - whose dependency rows reference objects the catalog doesn't contain (or - vice versa). The `unknown:` filter in - [graph-builder.ts:26-33](../packages/pg-delta/src/core/sort/graph-builder.ts) - silently drops such edges — masking the symptom, losing real ordering - information. -- **Latency**: 28+ queries contending for 5 connections ≈ six serial waves, - and each of the heavy queries (`pg_get_*def`, `aclexplode`, lateral joins) - pays planning and queueing overhead. `applyPlan` runs **three full - extractions** per apply: source + target up front - ([apply.ts:83-86](../packages/pg-delta/src/core/plan/apply.ts)) and a - post-apply verification extract - ([apply.ts:138-152](../packages/pg-delta/src/core/plan/apply.ts)). - -**Target.** The pg_dump-parallel model — one exported snapshot, N workers: +## 2. The two principles -```ts -// catalog.model.ts (sketch) -const lead = await pool.connect(); -await lead.query("BEGIN ISOLATION LEVEL REPEATABLE READ READ ONLY"); -const { rows: [{ snap }] } = await lead.query("SELECT pg_export_snapshot() AS snap"); - -const runExtractor = async (extract: (c: ClientLike) => Promise) => { - const worker = await pool.connect(); - await worker.query("BEGIN ISOLATION LEVEL REPEATABLE READ READ ONLY"); - await worker.query(`SET TRANSACTION SNAPSHOT '${snap}'`); - try { return await extract(worker); } - finally { await worker.query("COMMIT"); worker.release(); } -}; -// run all extractors (objects + depends + version + user) with bounded -// concurrency over the same snapshot, then COMMIT + release the lead. -``` +Everything in this design follows from two principles. -Every extractor sees the exact same database state; parallelism is preserved -(and improves, since the pool default rises to match the worker count). This -is days of work and fixes the bug outright. - -**Second step, only if profiling justifies it**: collapse the per-type queries -into ~6 "object family" queries returning `jsonb_agg` rows (relations, -routines, types, security, replication, misc), cutting round-trips ~5×. A -single mega-query is rejected — planner-hostile and unmaintainable. - -**Also**: make the post-apply verification extract **opt-in** instead of -opt-out (today it runs unless `verifyPostApply: false`, -[apply.ts:138](../packages/pg-delta/src/core/plan/apply.ts)). The plan's -fingerprint contract already guards pre-apply state; the third extraction is a -paranoia check that belongs in CI, not in every production apply. One-third -fewer extractions per apply. - -### 3.2 Content-hash equality - -**Problem.** `BasePgModel.equals` -([base.model.ts:70-75](../packages/pg-delta/src/core/objects/base.model.ts)) -delegates to `deepEqual`, which is -`stringifyWithBigInt(a) === stringifyWithBigInt(b)` -([objects/utils.ts:36-37](../packages/pg-delta/src/core/objects/utils.ts)) — -a full recursive `JSON.stringify` of both sides, recomputed for every shared -object on every diff. For a table model (columns, constraints, privileges, -security labels) that is a deep tree. At 10k shared objects, this dominates -diff CPU. `table.diff.ts` already works around it locally with -cheap-scalar-first comparisons — evidence the cost is real. - -**Target.** A memoized content hash on the base model: +### P1 — Postgres is the only elaborator -```ts -// base.model.ts (sketch) -abstract class BasePgModel { - #contentHash?: string; - get contentHash(): string { - return (this.#contentHash ??= hashCanonical(this.stableSnapshot().data)); - } - equals(other: BasePgModel): boolean { - return this.stableId === other.stableId - && this.contentHash === other.contentHash; - } -} -``` +The single deepest source of bugs in this tool class is reimplementing +PostgreSQL semantics: name resolution, type elaboration, dependency +inference, default normalization. The current codebase half-commits to this +principle (dependency edges come from `pg_depend`, never from parsing — the +right call) but still runs **three** semantic engines: -`hashCanonical` = canonical serialization (sorted keys, bigint-safe — the -existing `stringifyWithBigInt` semantics) fed to a fast non-cryptographic hash -(xxhash64 or FNV-1a). The hash is computed once per object, lazily, and -overlaps with extraction I/O wait. `stableSnapshot()` is already the correct -equality surface — subclasses override it to drop unstable fields (the -"physical attnums vs logical names" rule), so the hash inherits every -normalization for free. - -Two integration points: - -- `fingerprint.ts` already canonically stringifies models for plan - fingerprints; feed it the same canonical string so the work is shared (keep - SHA-256 there — fingerprints cross machine boundaries). -- Keep `table.diff.ts`'s scalar fast paths: they classify *what kind* of - ALTER to emit for objects already known to differ. The hash replaces only - the *are-they-equal* gate. - -Diff becomes O(n) 8-byte compares. Expected 5–20× on the diff stage at scale. - -### 3.3 Sort: build once, scan only what changed - -**Problems** (all in `src/core/sort/`): - -1. `convertCatalogDependenciesToConstraints` iterates **every** `pg_depend` - row in the catalog on every sort - ([graph-builder.ts:26](../packages/pg-delta/src/core/sort/graph-builder.ts)), - regardless of how many changes are being sorted. A one-change diff against - a 10k-object catalog (≈100k+ depend rows) pays the full scan — twice, once - per phase. -2. `sortPhaseChanges` re-invokes `attemptSortRound` from scratch after every - cycle-breaking change injection - ([sort-changes.ts:259-289](../packages/pg-delta/src/core/sort/sort-changes.ts)), - and `attemptSortRound` rebuilds all graph data each call - ([sort-changes.ts:161-167](../packages/pg-delta/src/core/sort/sort-changes.ts)). -3. `performStableTopologicalSort` keeps its ready-queue sorted with linear - scan + `splice`, and pops with `shift` - ([topological-sort.ts:33-52](../packages/pg-delta/src/core/sort/topological-sort.ts)) - — O(V²) exactly in the large-schema case where thousands of independent - nodes are ready simultaneously. -4. `logicalSort`'s comparator re-runs regexes per comparison - ([logical-sort.ts:71-73](../packages/pg-delta/src/core/sort/logical-sort.ts)). - -**Target**, in order of impact: - -1. **Pre-filter depend rows to the change set.** Index the phase's - created/required stable IDs first, then visit only depend rows whose - endpoints appear in that index. Sorting cost becomes O(changes · - avg-fanout) instead of O(catalog). This is the single biggest sort win and - makes the common dev-loop case (tiny diff, huge database) effectively - O(changes). -2. **Build the graph once per phase; patch on injection.** Cycle injection - adds a handful of changes — extend the adjacency/index structures - incrementally instead of rebuilding. Re-running `findCycle` after each - repair is fine (cycles are rare); rebuilding everything is not. -3. **Binary min-heap ready-queue** keyed by original index → O(E log V), - identical output order (the tie-break rule is unchanged). -4. **Parse stable IDs once** into structs before `logicalSort`'s comparator - runs (this falls out of typed stable IDs, §4.1). - -The phase structure, edge semantics, weak-edge filters, and cycle-breaker -logic are untouched; the existing sort test suite is the oracle. - -**Expected multipliers** (estimates, to be validated with a benchmark fixture -at ~10k objects): extraction 2–4×, diff 5–20×, sort 3–10× — compounding, -since they are different pipeline stages. +1. catalog extraction (exact), +2. pg-topo's libpg-query static analysis (approximate — quoted-identifier + normalization, signature inference, builtin-type filtering are all + heuristic recoveries of what Postgres already knows), +3. declarative apply's round-based retry, which is "ask Postgres for + forgiveness, one error message at a time" + ([round-apply.ts:252-281](../packages/pg-delta/src/core/declarative-apply/round-apply.ts), + worst-case O(n²) statement executions). ---- +The north star has **one**: every input state is resolved by an actual +Postgres instance. Live databases trivially; SQL files by applying them to an +ephemeral shadow database and extracting the result; the system's own output +by applying it to a scratch clone and re-extracting (§3.7). No static SQL +parser exists anywhere in the trusted path. Static analysis survives only as +a developer-experience layer (§4.4). -## 4. Simplicity track - -### 4.0 Where the volume is - -`src/core/objects/` = **256 source files / 31,162 LOC** + **127 test files / -18,505 LOC**, across 21 object-type directories (some hold multiple kinds: -`type/` → enum/composite/range; `foreign-data-wrapper/` → FDW, server, -foreign table, user mapping).

The discipline that keeps rules from degenerating +into code-in-disguise: functions appear only in predicate and template +slots, and every rule's claims are checked by the proof loop (§3.7) — a rule +that lies about cascades or alterability produces a state mismatch in CI, +not a latent bug. + +This replaces, outright: 21 per-type diff functions, 106 change classes, the +five per-`objectType` dispatch switches +([catalog.diff.ts:47](../packages/pg-delta/src/core/catalog.diff.ts), +[change-utils.ts:10](../packages/pg-delta/src/core/change-utils.ts), +[fingerprint.ts:88](../packages/pg-delta/src/core/fingerprint.ts), +[change.types.ts:65](../packages/pg-delta/src/core/change.types.ts), +[file-mapper.ts:59](../packages/pg-delta/src/core/export/file-mapper.ts)), +and the shared privilege/comment/security-label wrapper classes. Today that +surface is 256 files / 31,162 LOC of source in `objects/` alone; the rule +table plus models is estimated at a third of it. + +### 3.5 Atomic actions: maximal decomposition + +Every action is the smallest valid DDL unit: bare `CREATE TABLE`; every +constraint, default, FK, index, grant, comment, ownership change as its own +action. Each action declares `produces` / `consumes` / `destroys` (stable +IDs), plus the safety metadata from its rule. + +This is pg_dump's deep trick, adopted wholesale: **pg_dump has no +cycle-breaker module because at this granularity, cycles structurally cannot +form** for entire categories of dependencies (mutual FKs, FK-vs-drop +interleavings). The current codebase already half-believes this — the create +phase emits constraints as separate `AlterTableAddConstraint` changes +([table.diff.ts:84](../packages/pg-delta/src/core/objects/table/table.diff.ts)), +which is exactly why all three cycle breakers +([cycle-breakers.ts](../packages/pg-delta/src/core/sort/cycle-breakers.ts): +`tryBreakFkCycle`, `tryBreakPublicationColumnCycle`, +`tryBreakPublicationFkConstraintDropCycle`) live in the **drop phase**, where +compound `DROP TABLE` semantics create implicit edges. Worse, the system +currently fights itself: post-diff normalization *prunes* constraint drops +for compactness, then the cycle breaker *re-injects* them when compactness +creates a cycle. The north star resolves the tension in one direction: +decomposed by construction, compacted only where provably safe (§3.6 output +stage). + +Failure-mode analysis is the argument: with repair, a new cycle class means +a wrong/unsortable plan in production and a new hand-written breaker (the +git history is a string of exactly these fixes). With avoidance, the +worst case is a more verbose script. Verbosity is recoverable; wrongness is +not. + +### 3.6 One graph, one sort, then cosmetic compaction + +A single dependency graph over all atomic actions — drops, creates, alters +together. Edges come from three sources: the old state's dependency facts +(teardown ordering: an action destroying X follows everything that consumes +X), the new state's dependency facts (build ordering: an action producing Y +precedes everything consuming Y), and identity conflicts (drop of `X` before +create of new `X`). One deterministic Kahn pass (heap-based ready queue, +tie-break by phase weight → kind weight → name) replaces today's two-phase +sort + `invalidates` side channel + repair loop: an in-place mutation is +simply an action that destroys the old fact and produces the new one, and +the mixed graph orders its dependents' teardown and rebuild around it +naturally. + +**A cycle is a rule bug.** Cycle detection remains as an assertion with a +high-quality diagnostic, and as a property-test target — never as a runtime +repair subsystem. (Today: graph rebuilt from scratch on every repair round, +[sort-changes.ts:161-289](../packages/pg-delta/src/core/sort/sort-changes.ts); +full catalog depend-row scan regardless of diff size, +[graph-builder.ts:26](../packages/pg-delta/src/core/sort/graph-builder.ts); +O(V²) ready queue, +[topological-sort.ts:33-52](../packages/pg-delta/src/core/sort/topological-sort.ts). +All of it dissolves rather than getting optimized.) + +**Compaction** is the final, optional stage: merge adjacent actions into +idiomatic compound DDL (constraints inlined into `CREATE TABLE`, column +clauses folded) only when no graph edge crosses the merge boundary. It is a +peephole optimization on an already-correct sorted script — it can produce +ugliness, never wrongness. On by default for humans, off for machines. + +### 3.7 Plan and proof + +A plan is: ordered actions + source/target fingerprints (which are now just +fact-base hashes — same machinery as equality) + the safety report +aggregated from per-action metadata (locks, rewrites, data loss). + +**The proof loop is the architecture's keystone.** Because any state can be +materialized (template-cloned scratch DB) and re-extracted, the planner can +certify its own output: apply the plan to a clone of the source, extract, +hash-compare against the desired fact base. Zero diff = proven plan. This +inverts the correctness economy of the whole project: + +- **In CI**: property-based testing becomes the primary coverage engine — + generate schemas, generate mutations, roundtrip, assert fixpoint. The + hand-written per-type test matrix (127 test files / 18,505 LOC in + `objects/`, 63 integration files × 3 PG versions × 15 shards = 45 jobs) + shrinks to a thin integration ring around a generative core. +- **In production**: proof-on-shadow is an optional pre-apply step for + high-stakes targets. +- **For the rule table**: rules that misdeclare cascades or alterability are + caught as state mismatches the day they are written, not as field bugs. + +### 3.8 Execution + +Sequential, lock-aware, segmented: actions self-declare transactionality, so +the executor groups maximal transactional runs and isolates the exceptions +(`CREATE INDEX CONCURRENTLY`, …) instead of today's all-or-nothing single +concatenated script +([apply.ts:125-131](../packages/pg-delta/src/core/plan/apply.ts), with its +own `TODO` admitting the gap at +[apply.ts:122](../packages/pg-delta/src/core/plan/apply.ts)).

charset=UTF-8 Content-Transfer-Encoding: 8bit Engine: domains (+domain constraints via ALTER DOMAIN), enum/composite/ range types (enum growth as ADD VALUE subsequence algorithm), collations (collversion excluded), event triggers, rewrite rules, aggregates (reconstructed from pg_aggregate), partitioned tables (PARTITION OF / PARTITION BY with column inlining, pg_inherits edges, inherited column/index/trigger exclusion), replica identity, FDW/server/user- mapping/foreign-table, publications (object lists, column lists, row filters), subscriptions, memberships, default privileges, role configs. Structural fixes proven by the corpus: - OWNED BY as payload + ALTER SEQUENCE OWNED BY (pg_dump's model) — the auto edge cycled with column defaults; owned sequences cascade- suppress into their owning column/table drops - FK constraint drops are NEVER suppressed into table drops: mutual-FK teardown cycles become unconstructible (decomposition over repair) - forced dependent rebuild: surviving dependents of replaced/dropped facts (views/policies/indexes/...) drop+recreate recursively - releases[] edges: owner alters run before the old owner's DROP ROLE - routine def changes replace (return-type changes) + rebuild dependents - column type changes sandwich DROP DEFAULT / TYPE..USING / SET DEFAULT - extension-member objects resolve to their extension in pg_depend edges (index-on-extension-opclass ordering) - role drops emit DROP OWNED BY first; membership revokes CASCADE - subscription dbs: drop cleanup + clone presync (TEMPLATE skips shared catalogs) Harness: meta.json (isolatedCluster on a fresh cluster pair with role cleanup, minVersion), EXPECTED_RED ledger, fixture validity 195/195. Engine proofs: 346/390, triage continuing. --- packages/pg-delta-next/PORTING-agent1.md | 136 +++ packages/pg-delta-next/PORTING-agent2.md | 179 +++ packages/pg-delta-next/PORTING-agent3.md | 162 +++

SET delisting a dropped table/column) - planner: two generic edge rules — dependent teardowns precede in-place alters of their dependencies, and creates follow alters of their kept dependencies (guarded against the REPLICA IDENTITY USING INDEX inverse) - creates emit parents-first so partitioned-parent column inlining registers before child column adds ('column created_at already exists') - tie-break key zero-pads the action index (string '10' < '9' scrambled multi-spec sequences) - servers parent to the extension when their FDW is extension-owned; extension-member FDW references resolve to the extension (FactBase integrity error on postgres_fdw) - EXPECTED_RED: pin mixed-objects--enum-replace-with-dependents:reverse (ADD VALUE + same-transaction usage needs execution-context segmentation, target-architecture §3.7) - tests: corpus loader gains PGDELTA_NEXT_ONLY / PGDELTA_NEXT_SHARD for focused and parallel runs Validation: PG 17 and PG 15 both 390/390 engine proofs + 212/212 extract/loader/fixture-validity; unit 60/60; tsc + oxlint clean.

charset=UTF-8 Content-Transfer-Encoding: 8bit Addresses the design-review findings; the proof loop is the oracle (PG 15 and 17 both 390/390 corpus + 251 integration + 184 unit green, differential vs old engine 37/37 zero divergences). Architectural simplification (guardrail 3): - per-kind graph/suppression policy moved OUT of the planner body and INTO the rule table as KindRules flags: metadata, cascadesToChildren, rebuildable, suppressible (FK constraints), dropRootRedirect (OWNED BY sequences), defaclObjtype. plan.ts no longer holds METADATA_KINDS / CASCADING_PARENTS / REBUILDABLE / isFkConstraint / DEFACL_KIND lists, so adding a kind is self-contained in its rule entry. Proof harness (turn declared safety metadata into verified claims, §3.7): - relfilenode rewrite-observation: a kept table physically rewritten under no rewriteRisk-declaring action fails the proof. This surfaced real under-declarations — column rules now declare rewriteRisk for STORED generated columns and volatile-default ADD COLUMN; the enum value-set cast references its column so attribution maps to the table. - opt-in autoSeed: synthetic rows in empty kept tables give the data-preservation check teeth without a seed.sql. - single-round-trip table stats (kills the per-table N+1). Frontends / extraction: - shadow loader: isolatedCluster vs databaseScratch modes, pg_auth_members leak detection, mutual-FK split-your-FK diagnostic, source:sqlFiles provenance tag. - FactBase provenance (source) + extract({source}); snapshot capturedAt; snapshots load tagged source:snapshot. - security labels fully modeled: pg_seclabel/pg_shseclabel extraction + the securityLabel global rule + rendering (unit-proven; e2e gated on a dummy_seclabel image). - unresolvable pg_depend endpoints recognized by the resolver but unbuildable by the codec now emit a diagnostic (resolver/codec mismatch) instead of silently dropping. Policy / CLI: - DSL v2: three target* predicates unified into one { target: {kind,schema, name} }; the misleading global serializeParams export removed (the planner resolves params per fact). - CLI: --renames defaults to prompt; --accept-rename = closes the interactive loop; shared parseFlags removes per-command argv boilerplate. Hardening / docs: - enum rename-aside temp name bumps past any existing type (collision-safe). - differ kind-free grep guard (stage-4 gate). - COVERAGE.md: catalog coverage, deliberate exclusions, and the two known granularity deviations (composite-type attributes, publication table-filters remain payload blobs — correct but coarse; deferred with rationale rather than rushed).

Proven by the corpus + differential (PG 15 and 17 both 396/396 corpus + 257 integration + 189 unit; old-engine differential 39/39 zero divergences). New StableId kinds (codec + round-trip tests): - typeAttribute (schema, type, name) — a composite type's attribute - publicationRel (publication, schema, table) — a published table - publicationSchema (publication, schema) — a published schema (PG15+) Composite types: - attributes extract as typeAttribute facts parented to the type; the type payload no longer carries an attributes blob. - fresh types inline their attributes into CREATE TYPE AS (…) (delta-set); existing types are managed incrementally — ADD / DROP / RENAME ATTRIBUTE … CASCADE all work while the type is used by table columns and preserve the stored data (empirically verified). RENAME enables data-preserving composite-attribute rename detection (new capability — old engine forced a type rebuild). - ALTER ATTRIBUTE … TYPE is supported for unused composites and fails loudly with a remediation message for in-use ones (PostgreSQL forbids it there; CASCADE only reaches typed tables, not columns) — it never emits a statement that would fail at apply. Publications: - tables/schemas extract as publicationRel/publicationSchema facts; the publication payload no longer carries tables/schemas blobs. - fresh publications inline members into CREATE PUBLICATION FOR …; existing ones use ALTER PUBLICATION ADD/DROP. A per-table column-list / WHERE change replaces that member only (DROP TABLE + re-ADD) — eliminating the prior dual-SET redundancy and churning nothing else. Extraction perf: the five security-label resolver queries are now gated behind a single pg_seclabel/pg_shseclabel existence probe, so a label-free database (the common case) pays one round trip, not six. Coverage: extractor ring asserts the new facts; renames suite proves composite-attribute rename (data-preserving, in-use); 3 new corpus scenarios cover composite ADD/DROP (in-use, seeded), composite retype (unused), and publication column/WHERE change. COVERAGE.md + README updated to reflect granularity-one is now complete.

fix ALTER COLUMN TYPE policy/view deps (#263) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Swept the open supabase/pg-toolbelt issues and turned every diff/plan/apply behavior into a corpus scenario, verified on PG 15 and 17 (corpus 416/416 + 268 integration + 189 unit; differential vs old engine 43/43 zero divergences). Most were old-engine flaws the new architecture does not reproduce; #263 exposed a real gap, now fixed. Fix (#263 — ALTER COLUMN TYPE / DROP FUNCTION blocked by policy/view): - PostgreSQL rejects ALTER COLUMN … TYPE while a view, rule, or policy references the column (0A000). A column type change is an in-place alter, so it did not seed the forced-dependent-rebuild and the policy was only ALTER'd in place (the old engine's exact bug). rebuildsDependents is now KIND-SELECTIVE: it returns the dependent kinds to rebuild. column.type declares [view, materializedView, rule, policy] — those are dropped before the type change and recreated after; indexes/constraints are NOT force-rebuilt (PG rebuilds them itself, and dropping a PK with dependent FKs would cascade harmfully). The forced-rebuild fixpoint tracks restricted seeds vs full-destroy origins so the restriction applies only to the first hop. Verified-already-correct (old-engine bugs absent in the new architecture): - #286 domain CHECK constraint dependent of a replaced function — the generic forced-rebuild drops/recreates it (old engine skipped it). - #280 function signature change referenced by a column default / check constraint — the table is never dropped; the data-preservation proof on seeded rows confirms no recreation (old engine over-recreated the table). - #269 user object referencing an unchanged managed-schema object — the plan applies to a target that has it; no round-apply stuck statement. - #282 CREATE TYPE AS RANGE used by a table — first-class range fact with a column→type edge; the shadow loader orders the exact shuffled repro. The pg-topo classification bug does not exist in the new engine (no pg-topo in the trusted path, P1). - #219 GRANT/REVOKE on an enum-arg function — stable signature, no temp-schema artifacts. - #218 DEFERRABLE INITIALLY DEFERRED unique constraint — roundtrips via pg_get_constraintdef. New: 10 corpus scenarios + 1 shadow-loader test; COVERAGE.md gains a field-issue table. Chores #250/#244/#115 are resolved differently by the new design (benchmark harness, per-action transactionality, one graph/sort) — documented, no scenario.

We emit `pgmq.create(...)`, `cron.schedule(...)`, + `partman.create_parent(...)` — the declarations. Synthesizing the raw + `CREATE TABLE pgmq.q_jobs (...)` the extension produces would **reimplement + the extension**, which is version-fragile and violates P1 (§2). +3. **Row data is preserved, never moved.** The data-preservation proof (§6) + asserts messages and partition rows survive any plan that does not *intend* + to drop the queue/parent. We never copy rows; we only refuse to destroy them. + +--- + +## 2. Principles (the north-star principles, applied to intent) + +No new philosophy — the existing two principles applied to a second kind of +state. + +### P1 applied — capture and replay, never parse, never reimplement + +The deepest bug source is reimplementing PostgreSQL (or extension) semantics. +Intent is no exception, in **both** directions: + +- **Reading**: intent is *captured* from the extension's own catalogs + (`part_config`, `cron.job`, pgmq's `meta`) exactly as schema is read from + `pg_catalog`. We never parse a `cron.command`, an install script, or a + migration to *infer* intent. A `cron.command` we cannot introspect is treated + like a PL/pgSQL body — opaque, late-bound, ordered conservatively (§4.5). +- **Writing**: intent is *replayed* through the extension's own function. The + extension is the authoritative elaborator of its own objects — so replaying + `pgmq.create` is the same P1 move as letting Postgres elaborate a `CREATE + TABLE`, while emitting hand-built DDL for `pgmq.q_jobs` would be a private, + version-coupled reimplementation. + +### P2 applied — intent knowledge in exactly two forms + +Per-extension knowledge lives in exactly two forms, mirroring the rule table: + +1. **Capture queries** — extension catalog → normalized facts + edges. +2. **Intent rules** — intent-deltas → replay actions, with `consumes` / + `produces` / safety metadata, registered into the **one** rule table. + +Everything between (diff, ordering, proof, rename, safety) is the **same generic +machinery** the schema path uses. Supporting a new stateful extension means +writing one **handler** (a data package) and authoring zero engine code. + +### One fact base — "sidecar" is a contract, not a second pipeline + +Two things must both hold, and they are **not** a trade-off (the earlier draft +treated them as one — §10c): + +- **The core schema contract stays pure.** `src/core` extracts `pg_catalog` and + nothing else (P1, project `CLAUDE.md`); it never learns what a queue is. +- **There is exactly one fact model, one diff, one graph, one proof.** A + *second* fact relation with its own capture/diff/proof would reintroduce the + grain translation that §8.7 exists to eliminate (guardrail 8). + +The resolution: intent facts are **ordinary facts in the one fact base** — same +`Fact` shape, identity-free content hash, Merkle rollup, generic `Delta`, +one-graph sort, proof loop, rename machinery — but **produced by the integration +layer, not by core extraction**, and carrying **provenance** that excludes them +from the core schema contract. "Sidecar" means *who produces the fact and which +contract governs it*, not a separate structure. Core extraction reads +`pg_catalog`; an **integration-aware extract** additionally runs the registered +handler captures **under the same exported snapshot**; both fact streams land in +one fact base. Nothing downstream is duplicated, and §1/P1 hold because *core* +still produces only schema. + +--- + +## 3. What is captured per extension (the intent matrix, v1) + +An intent fact is identity-keyed and content-hashed exactly like a schema fact +(`target-architecture.md` §3.1): identity-free payload, so hash-equality drives +diff and rename. Identity uses a **single generic core kind**, +`extensionIntent`, parameterized by `ext` + `intentKind` + key — so the core +StableId codec gains *one* kind, not one per extension (guardrail 1 stays a +single codec). + +```ts +// canonical id: extensionIntent:{ ext, intentKind, key } +// e.g. extensionIntent:{ ext:"pgmq", intentKind:"queue", key:"jobs" } +``` + +### 3.1 pgmq + +```ts +{ ext:"pgmq", intentKind:"queue", key:, + payload: { type:"standard"|"unlogged"|"partitioned", + partition_interval?:string, retention_interval?:string } } +``` + +- **Capture**: read pgmq's queue registry (`.meta` / + `pgmq.list_queues()`), schema resolved dynamically via + `pg_extension`/`pg_namespace`. +- **Create**: `select pgmq.create('')` / `create_unlogged` / + `create_partitioned`. **Drop**: `pgmq.drop_queue('')` — + `dataLoss:"destructive"`. +- **Operational objects** (filtered, §4.3): `pgmq.q_`, `pgmq.a_`, + their indexes/sequences. +- **consumes**: none. **produces**: the queue intent fact + (via `managedBy` + edges) its operational objects. + +### 3.2 pg_cron + +```ts +{ ext:"pg_cron", intentKind:"job", key:, + payload: { schedule:string, command:string /* opaque */, + database:string, username:string, active:boolean } } +``` + +- **Capture**: read `cron.job`. **Ownership normalization (CLI-1435)**: jobs + created before the patch were owned by `supabase_read_only_user`; normalize + `username` to `postgres` on capture so a rebuild doesn't reproduce the legacy + owner.

A **user-declared** `PARTITION +OF` carries no `managedBy` edge, so its intended drop still fires — the #5491 +false-suppression regression cannot recur by construction. The signal is sourced +exactly where CLI-1591 requires it — the extension's own catalog, in the +integration layer, never `src/core`. + +### 4.4 One intent reader, three doors (the hybrid sourcing, made uniform) + +There is exactly **one** intent reader — `capture` — mirroring P1's "one +elaborator": + +- **Live DB**: `capture` reads the source's extension catalogs directly, under + the same exported snapshot as schema extraction (consistency — §3.2). +- **SQL files (shadow)**: the files contain the replay calls (`select + pgmq.create('jobs');` …). The shadow loader runs them; `pgmq.create` has DDL + side-effects but writes **no user-table rows**, so it passes the loader's + parser-free DML rejection. After loading, `capture` reads the **shadow's** + extension catalogs. Same reader. +- **Declarative block (deferred sugar)**: a typed `[extensions.*]` block that + `handler.materialize` would expand into the same replay calls against the + shadow before capture. **Deferred to B+** (§8): it is a *second representation* + of intent and the files path already works without it. + +Net: intent enters the system exactly one way — by being read from a Postgres +that actually holds it (live source, or a shadow built from the replay calls). +This is the same move P1 makes for schema, and it answers RFC open question #2 +(CLI-1431): the declarative source "format" is *the replay calls themselves*, +read back by capture — not a parallel semantics engine. + +### 4.5 The opaque-command strategy (the P1 honest cost, reused) + +`cron.command` and partman maintenance calls are opaque strings we refuse to +parse — the same blind spot `pg_depend` has for PL/pgSQL bodies +(`target-architecture.md` §7). Same layered defense: (1) order intent replay +conservatively late (a late tie-break weight in the one sort); (2) rely on +run-time late binding (a cron command resolves when it fires, not at apply); +(3) the **proof loop catches a genuine ordering gap before production** — a +replay call that fails against the clone fails the gate.

Proof (intent is proven, not just reported) + +The proof loop is the arbiter (guardrail 9), extended to intent because intent +is just facts: + +1. **State proof (schema)** — unchanged: apply, re-extract, hash-compare. + Operational objects are excluded on both sides (provenance), so they never + cause a false diff. +2. **Intent proof** — re-capture intent via the handlers and hash-compare against + desired. Zero intent diff = the replay reproduced the declared + queues/jobs/parents (and implicitly, their operational objects exist). +3. **Data-preservation proof** — the keystone. Distinguish two cases, because + they preserve data differently and the proof must check the right one: + - **Incremental apply** (target already has the managed objects): the filter + keeps them untouched, so seeded **queue messages** and **partition rows** + survive. Asserted directly. + - **Rebuild from empty** (branch creation): replay premakes *empty* children / + queues — correct under the schema-only contract (rows are seeded + separately, never moved by us). The proof asserts the *structure* is + reproduced, not that rows appear. + +The generative engine extends naturally: generate queues/jobs/parents, mutate +intent, roundtrip through the proof loop including data preservation. + +--- + +## 7. Plan artifact & safety surface + +Replay actions appear in the plan artifact like any action, carrying +`dataLoss`/`lockClass`/`transactionality`. So **Risk 2.0** (CLI-1459) covers +them for free: `pgmq.drop_queue` and a destructive `undo_partition` surface as +hazards in the same proof-verified safety report. No separate risk path. + +--- + +## 8. Honest costs & open questions + +- **Capture reads non-`pg_catalog` tables.** Strictly an integration-layer + capability (core forbids it).

Fact-level (not delta- level) keeps the proof honest: the plan you prove == the plan you run. - ExtensionHandler interface + extractWithHandlers (src/policy/extensions/): a generic, non-Supabase-coupled registry; core extract + handler captures into one fact base under the same snapshot. - pg_partman handler: reads .part_config + a recursive pg_inherits walk to tag every managed child (incl. *_default / premade). The only authoritative signal (relispartition / pg_depend can't tell a partman child from a user-declared PARTITION OF — CLI-1591). RED -> GREEN: - unit (src/policy/managed.test.ts): control proves a raw diff drops the child; with a no-op excludeManaged the exclusion asserts failed (Expected: false, Received: true) -> implemented -> 5/5 pass. A non-managed PARTITION OF removed on the desired side STILL drops (no false suppression). - integration (tests/extension-intent-partman.test.ts, supabase/postgres 17.6.1.135): against a real pg_partman parent+children, the raw diff drops the children; handler + excludeManaged stop it and preserve the parent. GREEN. Verified: 194 unit pass; check-types + format-and-lint + knip clean. Follow-up (next slice): compose handlers + excludeManaged into the CLI plan path and the provePlan re-extract; then Phase B (intent replay: create_parent / pgmq.create / cron.schedule).

Remediation plan responding to + `pg-delta-next-architecture-implementation-review.md` (external review) and my + per-point assessment of it. +- **Date**: 2026-06-13 +- **Branch / baseline**: `feat/pg-delta-next` @ `c9c322a`. +- **Governing doc**: `docs/target-architecture.md` (the north star). **This plan + does not amend it.** Almost every item here *closes a gap between the + implementation and what the north star already specifies* — explicit + projection (§3.9), proof tiers proven/observed/vetted (§3.7), + provenance-as-edges (§3.1), typed predicates over provenance edges (§3.9). Two + items (enum boundary, SQL-file txn) are robustness fixes within §3.8/§3.2. + +## Guiding principle + +The review's thesis is correct and is the organizing idea of this plan: **the +core diff/planner machinery is sound; the risk is safety semantics becoming +implicit at the boundaries** — extraction policy, proof coverage, frontend +loading. Every item below makes one boundary *explicit and auditable*. + +A note on what already converges: Phase A's `excludeManaged` +(`src/policy/managed.ts`) is a **fact-level** transform applied symmetrically to +source/desired/proof — chosen precisely because delta-level filtering drifts the +proof. That is the same conclusion the review reaches in finding #2. So Phase A +is not rework; it becomes one input to the projection layer (Item 1). + +--- + +## Work items + +Each item: the problem (with the review finding # and my verdict), the fix +*within the architecture*, files, tests/gates, dependencies, and effort/risk. +All work follows repo discipline: RED→GREEN, no SQL-byte assertions +(guardrail 6), corpus + differential gates, `private:true` so no changeset. + +### Item 1 — Explicit projection + projected target fingerprint (review #2, **strong agree**) + +**Problem.** `filterDeltas` removes deltas, but the plan's target fingerprint is +the *full, unprojected* `desired`. `provePlan` then diffs the clone against full +`desired` with no policy, so a policy-hidden delta makes the plan intentionally +not converge while the metadata still claims the unprojected target. Ambiguous +target = both a correctness risk and an explainability gap. + +**Fix (within §3.9 "baselines = fact-base subtraction; policy decides +visibility").** Introduce an explicit projection step that produces the state +the plan *actually targets*, and fingerprint/prove against that: + +```ts +interface Projection { + projectedSource: FactBase; + projectedDesired: FactBase; // == the honest plan target + ledger: ProjectionEntry[]; // every fact/delta removed, with reason +} +``` + +Two distinct, clearly-named mechanisms (the review collapses them; keeping them +separate is what makes the semantics crisp): + +- **Projection (fact-level, both sides, affects the fingerprint)** — "out of my + universe." Subtract facts from *both* source and desired so they never diff. + This is the home for: baseline (`subtractBaseline`), managed/operational + objects (`excludeManaged`, Phase A), system schemas/roles, and extension + members (Item 4). The target fingerprint reflects the subtraction. +- **Filtering (delta-level, "I see it, I won't act on this change")** — for + *verb-specific* suppression (the Supabase policy uses `verb` predicates). A + filtered delta MUST be reflected in the target: `projectedDesired` is the + fact base reached by applying only the **kept** deltas to `projectedSource` + (equivalently, `desired` with each filtered fact reverted to its source + value). So `fingerprint(projectedDesired)` is honest and + `diff(proven, projectedDesired) == ∅` is the real proof obligation. + +`plan()` computes `projectedDesired` and uses it for fingerprints; `provePlan` +targets it; both surface the `ledger` so "what was intentionally excluded, and +why" is reportable. + +**Files.** new `src/policy/project.ts` (compose baseline + managed + policy +projection + filtered-delta reversion → `Projection`); `src/plan/plan.ts` +(target fingerprint from `projectedDesired`; expose `ledger`); +`src/proof/prove.ts` (diff against `projectedDesired`); `src/plan/artifact.ts` +(serialize the ledger); public API in `src/index.ts`. + +**Tests/gates.** Unit: a fact-level projection rule removes a fact from both +sides → no delta + fingerprint reflects it; a verb-filtered delta → that fact +reverts to source in `projectedDesired`; the ledger records both with reasons. +Integration: a Supabase-style policy (exclude system schema + filter a `remove`) +→ `provePlan` converges to `projectedDesired`, not full desired. Full corpus +regression. + +**Depends on:** nothing. **Enables:** Items 2, 4b. **Effort/risk:** medium / +medium (touches the plan→prove contract; well-bounded by the proof gate). + +### Item 2 — Proof reports coverage; content fingerprints for seeded tables (review #3, **agree**) + +**Problem.** `provePlan` verifies drift deltas + row **counts** + `relfilenode`. +`autoSeed` is off by default and few scenarios ship `seed.sql`. Row-count +preservation ≠ content preservation (a lossy type change or truncate+reinsert +passes). The README overstates the guarantee. + +**Fix (within §3.7 proven/observed/vetted tiers).** Stop reporting a broad +boolean; report **what was actually checked**: + +```ts +interface ProofCoverage { + tablesChecked: number; tablesSkipped: Array<{ table: string; reason: string }>; + perTable: Array<{ + table: string; + contentMode: "fingerprint" | "count" | "none"; + recreated: boolean; rewriteDeclared: boolean; + rowsBefore: number; rowsAfter: number; + }>; +} +``` + +Add **deterministic content fingerprints** for seeded/non-empty kept tables +(`md5(string_agg(t::text, '\n' ORDER BY t::text))` before vs after) — a content +change on a `dataLoss:"none"` table is a violation, not just a count change. +Keep `autoSeed` opt-in (it is an audit mode), but the coverage report makes +"0 rows checked" honest so the verdict can't be misread. The verdict's `ok` +stays, but is now backed by an auditable coverage object. + +**Files.** `src/proof/prove.ts` (coverage + content fingerprint); README.md + +`API-REVIEW.md` (proof described as tiers + coverage — see Item 8); expand +`seed.sql` for the destructive corpus scenarios that most need content proof. + +**Tests/gates.** RED: a scenario that preserves row count but mutates content +(e.g. a column type change with a lossy `USING`) → today's proof says `ok`; with +content fingerprints it must FAIL. GREEN after the fingerprint check. + +**Depends on:** Item 1 (proof must target `projectedDesired`). **Effort/risk:** +medium / low. + +### Item 3 — Typed policy predicates + edge-kind in `edgeTo` (review #7, **agree, independently confirmed**) + +**Problem.** `idField` is stringly-typed (a typo silently never matches), and +`edgeTo` matches only the edge *target*'s kind/schema — **not** the edge's +`EdgeKind`. The latter is exactly why Phase A's `managedBy` filtering had to be a +fact-level transform instead of a policy rule. + +**Fix (this is literally §3.9: "typed predicates over fact kinds, identities, +provenance edges, and delta verbs").** Add `edgeKind?: EdgeKind` to +`EdgeToPredicate` and match it in `factMatches`. Add per-kind field-name +**validation** in `validatePolicy` (an `idField` naming a field the kind doesn't +have is a config error, not a silent no-match). Prefer typed identity-field +predicates where the kind is known. + +**Files.** `src/policy/policy.ts` (`EdgeToPredicate`, `factMatches`, +`validatePolicy`); `src/policy/policy.test.ts`. + +**Tests/gates.** `edgeTo: { edgeKind: "memberOfExtension" }` matches only those +edges; an `idField` typo throws in `validatePolicy`. **Depends on:** nothing. +**Enables:** Item 4 (provenance filtering as policy). **Effort/risk:** small / +low. *Good early win.* + +### Item 4 — Provenance as edges; filtering as projection (review #1, **agree; it's the documented end-state**) + +**Problem.** Extension-member objects are removed at extraction by +`notExtensionMember` anti-joins. This is the documented v1 stand-in +(`COVERAGE.md`), but it is **inconsistent** — a member object is filtered while +its ACL/comment satellite is not — which is the root of CLI-1471 (orphan `GRANT` +on an extension aggregate). Note: `managedBy` (Phase A) is a *sibling* of +`memberOfExtension`, not the same thing; this item is specifically about +extension **members**. + +**Fix — phased**, because the full flip has a large blast radius (every +extractor query) and a real cost (fact-base inflation): + +- **4a — extraction consistency (small, immediate correctness).** A satellite + (acl/comment/securityLabel) of a filtered object must itself be filtered. + Kills the orphan-satellite bug class (CLI-1471) now, independent of the flip. + Add a corpus scenario for the extension-member-aggregate GRANT. +- **4b — provenance edges (large, the north-star end-state, §3.1 "provenance is + data, an edge fact, not an extraction-time filter").** Stop anti-joining + members; extract them WITH `memberOfExtension` edges to the extension fact. + Projection (Item 1) + an edge-kind policy rule (Item 3) then excludes them. + This is the "observe everything, project intentionally" pillar. + +**Files.** 4a: `src/extract/extract.ts` (satellite emission gated on target +presence) — or rely on the existing missing-requirement guard and assert it. +4b: `src/extract/extract.ts` (remove `notExtensionMember`, emit +`memberOfExtension` edges across all extractor queries); `src/policy/supabase.ts` +(projection rule for `memberOfExtension`); `COVERAGE.md`. + +**Tests/gates.** 4a: CLI-1471 scenario — the aggregate's ACL is excluded with +its extension-member target; no orphan GRANT. 4b: extension-member objects +appear as facts with `memberOfExtension` edges; Supabase projection removes +them; full corpus + differential regression (this changes what enters the fact +base, so the differential oracle is the safety net). **Depends on:** Item 1 + +Item 3 (for 4b). **Effort/risk:** 4a small/low; **4b large/high** — recommend +landing 4a immediately and scheduling 4b as its own gated effort (it may even +be staged per extractor family). + +### Item 5 — `commitBoundaryAfter` becomes an unconditional segment boundary (review #6, **agree the concern; refine the fix**) + +**Problem.** `plan.ts:727` inserts the boundary "before the FIRST graph +successor" of a `commitBoundaryAfter` action. An `ALTER TYPE … ADD VALUE` is an +in-place `set` that *consumes* the type fact; a same-plan consumer of the new +value (e.g. a new column `DEFAULT 'newval'::myenum`) *also* consumes the type — +they are **siblings with no edge between them**, so the consumer may not be a +graph successor → no boundary → both land in one segment → `55P04`. + +**Fix.** The review's first option ("model enum labels as facts") **does not +help** — `pg_depend` never records per-label dependencies (everything points at +the type), so no finer edge would ever exist; this is not a granularity-is-one +violation. The correct, cheap fix is the review's second option: in +`segmentActions` (`apply.ts`), treat `commitBoundaryAfter` as an +**unconditional** close-the-current-segment boundary *after* the action, +independent of graph-successor shape. Simplify/remove the successor-search +boundary logic in `plan.ts`. Cost: at most one extra segment. + +**Files.** `src/apply/apply.ts` (`segmentActions`); `src/plan/plan.ts` (drop the +conditional boundary insertion); a new corpus scenario: a new enum value used by +a **new column default in the same plan**. + +**Tests/gates.** RED: the new corpus scenario fails under proof (or apply) today +if the consumer shares the segment; GREEN with the unconditional boundary. +**Depends on:** nothing. **Effort/risk:** small / low. + +### Item 6 — SQL-file shadow loading robustness (review #5, **partially disagree; narrower fix**) + +**Problem (corrected).** The review claims a multi-statement file can *partially* +apply. It mostly cannot: `client.query(file.sql)` uses the **simple** protocol, +which Postgres runs as a **single implicit transaction** — statement 2 failing +rolls statement 1 back, and the whole-file retry is clean. The *real* (narrower) +gaps are files containing **explicit `BEGIN/COMMIT`** (breaks the implicit +atomicity) or **non-transactional statements** (`CREATE INDEX CONCURRENTLY` +*errors* "cannot run inside a transaction block" and can never load). + +**Fix (hardening).** Wrap each file attempt in an explicit transaction/savepoint +and `ROLLBACK` on failure (makes the implicit guarantee explicit and robust to +embedded `COMMIT`). Detect non-transactional statements and either classify the +file with a clear diagnostic or strip/rewrite them — in a throwaway shadow, +`CONCURRENTLY` is pointless, so dropping the keyword is safe and lets such files +load. + +**Files.** `src/frontends/load-sql-files.ts`; loader tests (a mid-file failure +retries cleanly; a `CONCURRENTLY` file is handled, not stuck-forever). +**Depends on:** nothing. **Effort/risk:** small / low. + +### Item 7 — Planner internal module split (review #4, **partial agree; do last**) + +**Problem.** `plan.ts` carries many responsibilities in one module. This is +organization hygiene, **not** a locality violation — per-kind knowledge is +correctly in the rule table (guardrail 3); the planner is the generic machinery. + +**Fix.** Behind the **unchanged** public `plan()` API, extract internal modules +(`TransitionClassifier`, `RenameApplier`, `DependentRebuildExpander`, +`ActionEmitter`, `RequirementChecker`, `PlanGraphBuilder`, `Segmenter`, +`Compactor`, `SafetyReporter`). Pure refactor. + +**Files.** `src/plan/plan.ts` → split. **Tests/gates.** Full corpus + +differential must show **state-equivalent plans** (zero behavior change). +**Depends on:** Items 1, 2, 5, 6 ("after semantics settle"). **Effort/risk:** +medium / medium — defer until the semantic items land so we refactor a stable +target. **Lowest priority.** + +### Item 8 — Docs normalization (continuous) (review #8, **agree**) + +**Fix.** Normalize README / `API-REVIEW.md` / `COVERAGE.md` into three buckets: +**implemented & proven**, **implemented with known simplification**, +**deliberately out of the modeled universe**. `COVERAGE.md` is the source of +truth for exclusions. Fix the README proof overstatement (ties to Item 2). Do +this *as part of* each item above (each item updates the relevant bucket) rather +than as a separate pass. + +--- + +## Sequencing + +``` +Item 3 (typed predicates) ─┐ + ├─▶ Item 4b (provenance flip, large) +Item 1 (projection) ───────┘ + │ + └─▶ Item 2 (proof coverage) + +Item 4a (extraction consistency, CLI-1471) ── independent, quick win +Item 5 (enum boundary) ── independent, cheap +Item 6 (SQL-file robustness) ── independent, cheap +Item 7 (planner split) ── after 1,2,5,6 +Item 8 (docs) ── continuous, folded into each item +``` + +**Recommended order:** + +1. **Item 1 + Item 2** — the coupled, highest-leverage pair (explicit target + + honest proof).

Sequencing: + hardening first, then resume Phase B. + +## Risk register (accepted honest-costs, not work items) + +The review did not raise these; they are documented north-star costs and belong +on the same "implicit safety at the boundary" register — monitored, not fixed: + +- **`pg_depend` routine-body blind spot** (§7): PL/pgSQL and string-literal SQL + bodies are not dependency-tracked, so body-referenced ordering relies on + `check_function_bodies=off` + the proof loop catching gaps. No body parsing in + the trusted path (P1). +- **Rename cross-reference caveat** (§4.1): a rename of an object referenced *by + name* in another payload (an FK naming its table) degrades silently to + drop+create, never the reverse. + +## Done-when + +- Projection is an explicit, reported step; `provePlan` targets + `projectedDesired`; "what was excluded and why" is in the plan artifact. +- Proof emits a coverage report; seeded tables are content-fingerprinted; a + count-preserving content mutation is caught; README/API docs match. +- Policy predicates are typed and validated; `edgeTo` filters by `EdgeKind`. +- Extension-member satellites can no longer orphan (CLI-1471 scenario green); + (4b) members are facts with `memberOfExtension` edges, projected by policy. +- `commitBoundaryAfter` always closes its segment; the same-plan enum-consumer + scenario is green. +- SQL-file attempts are transactional; non-transactional statements are + classified/handled, never silently stuck. +- Full corpus green on PG 15 + 17; differential clean; lint/types/knip clean at + every commit. From c107696d6dec8cfded9d64af4229377b31ccc676 Mon Sep 17 00:00:00 2001 From: Julien Goux Date: Sat, 13 Jun 2026 23:07:19 +0200 Subject: [PATCH 030/183] feat(pg-delta-next): project the plan target through policy filtering (review #2) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit filterDeltas removes deltas the plan won't apply, but the plan still has a real target: the state reached by applying only the KEPT deltas — `desired` with each FILTERED delta reverted to its source value. Previously target.fingerprint was the full, unprojected desired, and provePlan diffed against it, so a policy-hidden delta made the plan intentionally not converge while the metadata claimed the unprojected target (ambiguous proof target). - src/plan/project.ts: projectTarget(desired, filteredDeltas) — reverts add (delete), remove (restore source fact), set (revert attr to `from`), link (drop edge), unlink (restore edge); cleans up orphaned subtrees + dangling edges. Needs no source: each delta carries its source-side data. - plan(): target.fingerprint = projectedDesired.rootHash. - provePlan(): drift is diffed against projectTarget(desired, plan.filteredDeltas). No-op when filteredDeltas is empty (early return), so policy-free plans and the whole corpus are byte-identical. RED -> GREEN: project.test.ts — stub no-op failed the per-verb revert asserts and the plan-fingerprint assert (target == desired, expected == source); real impl green (6/6). Verified: 200 unit pass; partman prove integration 2/2; differential slice 15/15 both-converge; lint/types/knip clean.

The proof now: - computes a deterministic content fingerprint (md5 over order-independent row text) for every NON-EMPTY table, plus a column schema signature; - flags a data violation when the count holds but CONTENT changed while the schema signature is UNCHANGED (genuine data mutation). A schema change — including a column propagated from a partitioned parent — legitimately changes whole-row text, so such tables are count-checked only (no false positive); - emits an honest per-table ProofCoverage (tablesChecked, tablesSkipped with reason, and contentMode fingerprint|count|none) so `ok` is backed by what was actually verified, not a bare boolean.

ADD VALUE is unusable before COMMIT, so nothing after it may share its transaction. The boundary previously relied on the planner marking the ADD VALUE's first GRAPH SUCCESSOR (newSegmentBefore) — but a new consumer of the value (e.g. a new column DEFAULT 'newval') has no pg_depend edge to the ADD VALUE (pg_depend is type-grained, not label-grained), so no successor is marked and no boundary is inserted → 55P04 at apply. segmentActions now closes the transactional segment AFTER every commitBoundaryAfter action, unconditionally, independent of graph-successor shape. (The review's other option — modeling enum labels as facts — would not help: there is still no catalog edge to a label.) The existing newSegmentBefore path is kept for compaction protection. New corpus scenario type-ops--enum-add-value-used-in-new-column: a new enum value used as a new column's DEFAULT in the same plan. The NEW engine converges (ADD VALUE sorts before the column via kind-weight tie-break, then the boundary commits it); the OLD engine fails with `unsafe use of new value "meh"` — old-fails-new-converges, a demonstrated improvement.

In practice PostgreSQL runs a multi-statement simple query as one implicit transaction, so ordinary files were already atomic — but that relied on a protocol detail, not our code. applyFile now wraps each file in an EXPLICIT BEGIN/COMMIT with ROLLBACK on failure, making clean retry our guarantee. A statement that cannot run inside a transaction block (CREATE INDEX CONCURRENTLY, …) — which the new wrapper would otherwise break — is re-run RAW on the throwaway shadow, detected by EFFECT (SQLSTATE 25001), never by parsing (P1). Tests (tests/load-sql-files-atomicity.test.ts): a file whose 2nd statement fails leaves no partial state and retries cleanly across rounds (would fail "relation already exists" if statement 1 leaked); a single CREATE INDEX CONCURRENTLY file loads via the raw fallback (exercises the new path — the wrapper alone would 25001).

TYPE that only changes typmod, e.g. numeric -> numeric(12,4) (9.9 -> 9.9000): atttypid unchanged, atttypmod changed. Both were flagged as false content (data-loss) violations. Two corpus scenarios were RED on the branch as a result (composite-alter-attributes, alter-table--column-type-cast) — confirmed failing on baseline (pre-Stage-0 stash), so this is a defect in the delivered Item 2, not Stage 0: drift: (empty) data: test_schema.priced: 1 -> 1 rows Fold the composite type's attribute signature (one level) and atttypmod into schemaSig, so such changes flip the table to count-only. Adding signal to schemaSig can only turn a content comparison into a count comparison, never the reverse — it cannot mask a real mutation on an unchanged column. Both scenarios now pass on PG15 and PG17.

Extension-owned objects carry a `memberOfExtension` edge (target-architecture §3.1 "provenance is data, an edge fact"); they are out of the managed universe, so they must be projected away by default — on BOTH sides — exactly as `excludeManaged` handles `managedBy`. - src/policy/extension-members.ts: `excludeExtensionMembers(fb)` removes a fact with an outgoing `memberOfExtension` edge plus its descendant subtree (ACL/comment satellites ride as children, so they go too) and prunes dangling edges. Early-exits unchanged when nothing is a member. - plan(): projects source + desired before diffing, so members never produce deltas/actions and the target fingerprint reflects the projected state. - provePlan(): projects the proven re-extract AND the target, so a post-flip re-extract that observes members does not read them as drift. The projection lives at the plan/prove choke points, NOT in extract(): extract() stays "observe everything", plan/prove "project by default" — the two halves of the acceptance criterion. It is a verified no-op until the extractors emit the edges (Stage 2): full corpus is green on PG15 and PG17 (the no-op gate; both versions independently 418/418 after the schemaSig fix), and excludeExtensionMembers returns its input unchanged when there are no memberOfExtension edges (stock postgres). Stage 1 adds tests/extension-member-parity.test.ts: an INDEPENDENT pg_depend oracle that, family by family, asserts (soundness) every observed member is tagged and (completeness, per FLIPPED_KINDS) every catalog member is observed. Validated against a real Supabase extraction; passes vacuously pre-flip. FLIPPED_KINDS grows in Stage 2.

The member objects are observed by extract() and projected out by default in plan()/prove() (Stage 0) — the two halves of the acceptance criterion. Gated by tests/extension-member-parity.test.ts, an INDEPENDENT pg_depend oracle (soundness: every observed member is tagged; completeness: every catalog member of a FLIPPED kind is observed). The harness has teeth — verified it goes RED (154 routine members missing) when a family is unflipped, GREEN after. Refined the oracle to match the extractor's scope (user schemas, non-plpgsql, internal-dependency functions excluded, table rowtypes excluded). pg_partman/hstore/citext members on the Supabase image exercise the table/type/routine paths. The pre-existing partman test (real members) still passes; full unit suite + lint/types/knip clean. Deferred (regression-free, documented): sub-entity families (columns, constraints, indexes, triggers, policies, rules — their members ride out with the projected parent) and rare member-root kinds (fdw, server, foreignTable, eventTrigger, publication) keep their anti-joins. They retain today's filtering, so the projected default behavior is unchanged.

charset=UTF-8 Content-Transfer-Encoding: 8bit Deliberate dependency-resolution decision for the provenance flip. Now that extension members are observed as facts (Stage 2), a reference INTO a member (a user table column of an extension type, a default calling an extension function) could in principle resolve to the member fact. It must NOT: the member is projected out by default, so a member-targeted edge would be pruned with it and the dependent would silently lose its "create the extension first" ordering. The pg_depend resolver's existing collapse — member reference → the EXTENSION — points at an object that survives projection, so ordering holds. Keep it. - Correct the pg_proc / pg_type resolver comments (they said members "are not facts"; post-Stage-2 they are — the collapse is now an ordering choice, not a fact-existence fact). The fdw branch comment stays accurate (the fdw family is deferred, so fdw members really aren't facts). - tests/extension-member-ordering.test.ts: a table using citext (an extension-owned type) is ordered AFTER the extension and proves clean end to end (a table built before its extension would fail to apply). - COVERAGE.md: extension members are now "observed, projected by default"; document the flipped families, the ordering decision, and the deferred families (sub-entities + rare member-root kinds).

Ownership becomes an edge (`ownedBy`), not a payload string + +Today `schema.create` reads a payload `owner`, emits `AUTHORIZATION ` + +`consumes: role`, and `skipAuthorization` (rules.ts:584) suppresses the clause. + +**New model:** ownership is an edge `object --ownedBy--> role`, emitted by the +extractor wherever `pg_catalog` has an owner column (`nspowner`, `relowner`, +`proowner`, `typowner`, …). Consequences, all structural: + +- Projecting a role out of the view **prunes the `ownedBy` edges to it + automatically** — the projection already "prunes edges with removed + endpoints." A surviving object whose owner is out of scope simply has no + in-scope `ownedBy` edge. +- A create/alter rule renders owner **iff an in-scope `ownedBy` edge exists**. + No edge → no clause. **`skipAuthorization` ceases to exist** as a structural + consequence of edge pruning — it is not "fixed," it is gone. +- Owner *changes* become edge deltas (`unlink`/`link` → `ALTER … OWNER TO`), + and owner becomes **rename-aware**, uniformly, for every ownable kind. +- Per-kind owner SQL (`AUTHORIZATION` inline for schema; `OWNER TO` follow-up + action for most kinds, compactable into the create like column folds) lives in + the rule table. The planner holds no owner logic. + +### 2. Object-intrinsic render flags become fact fields, from the catalog + +`skipSchema` (rules.ts:604) encodes a property of the *extension* +(`pg_extension.extrelocatable`) that was never extracted, so the policy +hardcodes the answer (`["pgmq","pgsodium","pgtle"]`). + +**New model:** extract `extrelocatable` onto the `extension` fact. The extension +rule emits `SCHEMA` **iff the extension is relocatable**. No param, no name list, +**not Supabase-specific** — correct for PostGIS, uuid-ossp, anyone. (A +non-relocatable extension creates its own schema; a relocatable one is the only +kind that honours a `SCHEMA` clause.) + +*Principle: a serialize param that describes the object is a missing fact field.* + +### 3. Applier capability becomes a probed fact; the view is capability-restricted + +This is the irreducible residue, and the genuinely new idea. `skipAuthorization`'s +*real* cause is not the schema — it is that **the applier cannot become that +role**. The FDW-ACL exclusion (Supabase Rule 9) has the identical shape: **the +applier is not superuser**, so `GRANT ON FOREIGN DATA WRAPPER` is unexecutable. +Neither is derivable from the object catalog or from scope — both are properties +of **who is applying**. + +**New model:** probe the applier's capabilities at connect time and represent +them as facts — exactly as the schema is extracted: + +```ts +interface ApplierCapability { + role: string; + isSuperuser: boolean; + memberOf: ReadonlySet; // roles the applier can SET ROLE to + // derived helpers: + canActAs(role: string): boolean; // isSuperuser || memberOf.has(role) + canGrantOn(kind: FactKind): boolean; // superuser-gated kinds (fdw, …) +} +``` + +The view is then `view(facts, policy, capability)`, and capability-blocked +operations are **projected out of the view with a reported diagnostic, never +silently**. `skipAuthorization` and the FDW-ACL rule both *derive* from one +probed capability model instead of being hand-set per platform. For a pure +file-to-file diff with no applier connection, capability defaults to +"unrestricted" and apply-time failures surface loudly (documented). + +### 4. Filtering collapses to one grain + +The policy DSL **survives unchanged as composable data**; only its *compilation +target* changes — it compiles to a view transformation, not a post-diff filter. + +- **Scope rules (no `verb`)** — "exclude system schemas / system-role-owned / + satellites on managed objects" (Supabase Rules 4,5,6,7,10) — become + **fact-level projections** on both sides. Satellites and owner-edges then + follow their target out *by pruning*, so Rules 5/7/10 evaporate (a satellite + rides out with its parent automatically). **Stranding is impossible here.** +- **Operation rules (`verb`-bearing)** — "never DROP this", "create-only" — are + the only rules that need the diff, and each reduces to a **pre-diff adjustment + of the desired view relative to source**: `don't-drop` = copy the fact into + desired; `don't-create` = remove it from desired; `don't-alter` = pin source's + value.

The SCHEMA clause is now derived from the extension's pg_extension.extrelocatable fact — a relocatable extension emits SCHEMA and orders after that schema; a non-relocatable extension emits a bare CREATE and requires no schema. Removes the skipSchema serialize param (KNOWN_PARAMS) and the Supabase Old-14 rule with its [pgmq, pgsodium, pgtle] name list. No name list, nothing Supabase-specific. RED: a non-relocatable extension threw `missing requirement: CREATE EXTENSION "pgmq" SCHEMA "pgmq" consumes schema:pgmq`. GREEN: bare create, no requirement. Proven: unit (src/plan/extension-relocatable.test.ts), full unit suite 227/227, e2e (tests/extension-relocatable.test.ts) — hstore (relocatable) roundtrips with SCHEMA on alpine; pgmq (non-relocatable, self-schema) roundtrips with a bare CREATE on the Supabase image, applied to a clone with no pgmq schema beforehand.

The policy's scope (non-`verb`) filter rules are applied as a fact-level projection on BOTH sides (and the proof re-extract), so the proof stays honest by construction; `verb` rules remain at the delta level (filterDeltas). `resolveView(fb, policy)` = extension-member projection + scope projection; with no policy it is exactly excludeExtensionMembers, so the corpus path is unchanged. First-match-wins is preserved with over-projection safety: a fact is projected out only when certain ALL its deltas are excluded — an operation (`verb`) `include` earlier in the list (e.g. Supabase "include extension add/remove") protects a fact a later scope `exclude` (e.g. "exclude owner ∈ system roles") would remove. Under-projection falls back to the existing delta-level filter (safe); over-projection would silently drop managed objects. plan() and provePlan() apply resolveView symmetrically (provePlan gains a `policy` option). Scope exclusion is now observable via the view (a scope- excluded object is absent from plan.actions/target), not via filteredDeltas. Proven: resolveView unit tests incl. the operation-include safety case; full unit suite (235); policy integration suite (5); full corpus 418/418 on PG17 (no-policy path unchanged).

Answer, after analysis + empirical check: KEEP Rule 9. - Verified empirically that a non-superuser CANNOT GRANT on a FOREIGN DATA WRAPPER (tests/capability.test.ts), confirming the capability isSuperuser gate and Rule 9's stated rationale. - Capability (move 6) derives Rule 9's rationale precisely (drops FDW ACLs when the applier is non-superuser). At parity with Rule 9 for the real Supabase flow (local + Cloud postgres are non-superuser). DIVERGES for a superuser applier: capability would correctly MANAGE the FDW ACL; Rule 9 excludes unconditionally. - Rule 9 is a SELF-CONTAINED policy guarantee (holds even if a caller forgets to pass capability); capability depends on every caller supplying it. Retiring Rule 9 would weaken an unconditional guarantee into a fragile caller obligation (CLI-1469 regression). So retiring is a robustness regression. Conclusion: capability is the general mechanism (any non-superuser, any policy, + owner residue); Rule 9 is the Supabase policy's unconditional belt-and- suspenders. Complementary, not redundant — documented in supabase.ts + the managed-view doc.

Fixes a real probe bug the change exposed: probeApplierCapability returned the ARRAY(...) subquery as the unparsed text literal "{role}" (a name[] node-pg doesn't auto-parse), masked by the old `new Set(string)` (a Set of characters) + a weak `instanceof Set` assertion — so canSetOwner silently never matched a real probe. Cast rolname::text so node-pg parses it to a string[]. - Plan gains `capability?` (inlined like `policy`); plan() stores it; parsePlan round-trips it natively (artifact round-trip test added). - provePlan now defaults policy AND capability to the values inlined on the plan (options.x ?? thePlan.x), so a separate prove/apply invocation recovers the exact same view without re-supplying them. - CLI `plan --restrict-to-applier` probes the source connection's capability and threads it (opt-in; default off preserves behaviour for source≠applier flows). `diff` stays a raw delta dump (no view) by design; `apply` runs the baked actions; `prove` recovers capability from the artifact. Proven: full unit suite (245, incl. artifact capability round-trip); capability + owner-edge integration (6, probe returns a real string[] containing the role). Additive + gated → corpus no-op (re-confirmed separately).

Finding: the engine + its validation harness are essentially v1-ready — managed-view (moves 1-7 + follow-ups) shipped; corpus 211x2 under the proof loop on PG 15/17/18 in CI with EXPECTED_RED empty; a new-vs-old differential with a hard regression gate; a generative soak with an enforced kind-coverage checklist; reviewed public API. The ONE genuine correctness blocker is silent omission: the engine drops user-created objects in kinds it doesn't model (CAST, operator class/family, text-search config, statistics, language, transform) without telling anyone. Added docs/remaining-work/v1-unmodeled-kind-detection.md with the optimal fix — a provenance-aware catalog completeness check (diagnostic + opt-in strict mode): every managed-namespace object is modeled OR reported, never silently missed. v1 detects them; modeling each kind is demand-driven post-v1. Reframed the roadmap (overview + remaining-work/README) into: v1 correctness blockers (the detection gap + run the gates to green at scale + publish the scope statement) → post-v1 milestone A performance (parallel snapshot extraction, depend tuning, publish benchmark) → post-v1 milestone B DX & cutover (CLI productization, extension-intent Phase B, stage-10).

(See [archive/v1-readiness-review.md](archive/v1-readiness-review.md) +for an independent assessment.) + +--- + +## 5. What it does better — and differently + +**Correctness is mechanical, not aspirational.** The proof loop is the keystone: +a rule that emits wrong DDL is caught in CI when the clone fails to converge or a +seeded row vanishes — not by a user in production. This *inverts the correctness +economy* of the whole project. + +**The managed view is one definition, not three mechanisms.** Scope filtering, +ownership, and "what can this applier actually execute" used to be three +inconsistent code paths (`excludeManaged`, `excludeExtensionMembers`, post-diff +`filterDeltas`) plus serialize escape-hatch params. They collapse into a single +`resolveView(facts, policy, capability)` applied identically before `plan()` and +`prove()` — so the plan you prove is exactly the plan you run. See +[architecture/managed-view-architecture.md](architecture/managed-view-architecture.md). + +**It never silently misses your schema.** If you created an object in a kind the +engine doesn't model (a custom cast, operator class, text-search config, …), the +old engine would simply not see it. The new engine runs a provenance-aware +*catalog completeness check* and reports it as an `unmodeled_kind` diagnostic; +`--strict-coverage` refuses to plan while unmanaged user objects exist. Honest by +construction: it manages X, or it tells you it doesn't. + +**Ordering is correct by construction.** No cycle-breaker registry that grows by +one entry per field-discovered cycle — at fact grain there are no cycles to break. + +**The core library is lean.** `createPlan` consumers no longer pull a WASM SQL +parser into the trusted path. PostgreSQL does the elaboration. + +**It resolves most known issues by design.** Of **134 tracked issues** in the +diffing-2.0 project, roughly **90 are resolved by construction, by the corpus, or +by policy** rather than by porting individual fixes — the architecture dissolves +whole classes of bug. See [archive/linear-assessment.md](archive/linear-assessment.md). + +--- + +## 6. What is deliberately the same — and out of scope + +Honest boundaries matter as much as the wins: + +- **Same 7-stage pipeline shape and the `creates/drops/requires` change + contract** — this was the old engine's genuinely good idea; the rebuild keeps + it and makes the layers generic. +- **Detection, not modeling, of rare kinds** — v1 does not *model* casts, + operators, text-search objects, statistics objects, user languages, or + transforms. It *detects and reports* them (above). Modeling is demand-driven, + post-v1. +- **Data diffing (DML) is permanently out of scope** — this is a schema tool. +- **Performance is not yet a v1 gate.** v1 is cut on *correctness*; the new + engine may still trail the old one on raw speed until the performance milestone + (parallel snapshot extraction, `pg_depend` tuning).

This overturned the roadmap's assumption that parallel snapshot extraction was the big win (Amdahl: parallelizing the other 14% caps at ~10%). Rewrite the resolver set-based: one derived table per branch, built once over its catalog, hash-joined to the distinct endpoint set; a classid CASE picks the result (the classid gate on every join also prevents cross-catalog OID collisions). A single extm join over pg_depend deptype='e' replaces the six nested extension-member subqueries. The json_build_object shapes are byte-identical, so the library-side toId() decoder is unchanged. resolver query 1434 -> 204 ms (7.0x) extract (cold) 1881 -> 453 ms (4.2x) extract (mutated) 1523 -> 323 ms (4.7x) Also add an opt-in extraction statement-timeout budget: extract(pool, { statementTimeoutMs }) sets SET LOCAL statement_timeout and raises ExtractionTimeoutError naming the query that blew the budget, instead of an opaque cancel or indefinite hang (default unlimited — a legitimate large extraction is never aborted unless the caller opts in). benchmark.ts gains PGDELTA_BENCH_PER_QUERY=1 for reproducible per-query attribution. Validation: edge-set oracle byte-identical; extension-member parity tests green; full corpus 418/418 on PG15/17/18; check-types/lint/knip clean. Docs: milestone-A roadmap rewritten to record that profiling redirected the effort to the resolver query; parallel snapshot extraction deferred with the re-profile number (the resolver now caps its ceiling at <2x) in tier-4-deferrals.md.

charset=UTF-8 Content-Transfer-Encoding: 8bit Make docs/overview.md the comprehensive presentation centerpiece and fix a credibility-risk inaccuracy: the headline pie chart had mixed with-test numbers into a source-only total ("92% boilerplate"). Corrected against freshly verified counts: - objects/ = 31,162 LOC / 256 files = 58% of 53,933 source LOC (not 92%) - new engine = 11,471 LOC / 46 files - corpus = 209 scenarios / 418 cases (was "211"; also fixed in roadmap/README.md and roadmap/v1.md) - dropped the stale "parallel snapshot extraction is the upcoming win" framing Added for comprehensiveness: a concrete "these weren't theoretical" failure table (pg_partman/pgmq data loss, cache-lookup races, wrong signatures, cycle re-injection) mapped to structural cause; a new "Performance and memory, measured" section (profile-first story, 4.2×/7× table, parallel-extraction defer, ~660 B/fact memory + streaming roadmap); an extension-intent callout, a managed-view before/after (skipAuthorization -> ownership-as-edge), the differential/generative harnesses explained, an honest "what v1 doesn't do yet" table, and resolveView in the pipeline diagram. Also add the memory-optimal extraction/diff design doc (docs/roadmap/tier-3-extract-memory.md): two-pass hash-manifest -> fetch-changed to make held memory O(changes); Phase 1 (cursor-stream the unbounded extractors + maxFacts guard) is the low-risk OOM-relevant win, gating the full manifest diff on a real large-catalog need. Document the extm single-membership invariant in the resolver SQL.

P0: - depends-edge requirement invariant (internal.ts): buildActionGraph now fails loud when a produced fact's `depends` edge resolves to something neither produced nor present in source — a policy that filters a dependency's creation can no longer emit a migration referencing a missing object. - view-aware fingerprint gate (apply.ts, prove.ts): apply() reconstructs resolveView(current, policy, capability, baseline) before comparing, instead of gating the raw re-extract against the resolved-view fingerprint (which rejected valid scoped plans, and broke for any DB with extension members); prove passes baseline; both fail loud if a baseline-shaped plan has no baseline. P1: - foreign-table CHECK constraints extracted (relkind 'f') + serialized via ALTER FOREIGN TABLE (extract.ts, rules.ts). - non-transactional apply: RESET ALL in finally; a failed action is inDoubt. - SQL-file shared-object leak detection made symmetric (DROP/REVOKE/admin_option). - system-schema endpoints resolve to "skip" so they don't flood the diagnostic stream with dangling_edge noise (edge set unchanged). P2/P3: - proof seeding uses a collision-free tuple key (no split(".")); - export paths encode identifier segments + assert they stay under outDir; - check_function_bodies reset in finally; non-transactional file fallback rejects multi-statement files; idle pool errors logged via debug (credential-free). Docs: archived the review with its disposition; corrected stale metrics (corpus 210/420, API-REVIEW baseline/capability, PORTING security labels, roadmap links, extract.ts stage comments, COVERAGE scope table); added a contributor onboarding map and the engine-refactors roadmap (which records that the projectedDesired- canonical refactor is deliberately NOT taken — it would regress the P0-1 fix). Validated: corpus 420/420 on PG 15/17/18; 263 unit tests; check-types/lint/knip clean.

I prioritized the new `packages/pg-delta-next` implementation and the docs that explain its architecture and roadmap. + +## Executive summary + +The rewrite has a strong core shape. The `FactBase` / `StableId` / dependency-edge model is a good deep Interface: it gives the planner, proof loop, corpus runner, and SQL-file frontend a shared vocabulary without forcing each part to understand every catalog detail. The corpus/proof machinery is also a strong choice: it turns "we think this migration is equivalent" into a mechanically checked claim against a real database. + +I did find several correctness issues that should be fixed before treating the branch as complete. The most important one is that policy-filtered planning currently computes a projected target fingerprint, but still emits actions and builds the dependency graph against the unprojected target. That can produce migrations that reference objects whose creation was filtered out, and the planner does not reject the plan. I also found an extractor coverage gap for constraints on foreign tables, an apply/proof fingerprint mismatch for policy and baseline-shaped plans, non-transactional apply failure-reporting issues, and SQL-file frontend edge cases around shared-object leakage and path safety. + +Most of these are not signs that the architecture is wrong. They are places where a good abstraction is being bypassed or only partially applied. The main improvement theme is: once a view of the catalog has been resolved, make that view the only source of truth for the rest of the pipeline. + +## Validation performed + +The following local checks passed after installing dependencies: + +| Check | Result | +| --- | --- | +| `cd packages/pg-delta-next && bun run check-types` | Passed | +| `cd packages/pg-delta-next && bun test src/` | Passed, 261 tests | +| `bun run format-and-lint` | Passed | +| `cd packages/pg-delta-next && PGDELTA_NEXT_ONLY=foreign-data-wrapper-operations--full-lifecycle PGDELTA_TEST_IMAGE=postgres:17-alpine bun test tests/engine.test.ts` | Passed | + +I also ran two targeted probes: + +- a policy-filtered planner probe showing a table can be emitted with a column type provided by an extension whose `add` delta was filtered out; +- a PostgreSQL/testcontainers extraction probe showing a foreign table check constraint exists in `pg_constraint` but is not extracted as a constraint fact. + +I did not run the full corpus, the full differential/generative suite, or a long-running performance profile.

They share the scope, SQL fragments, and a mutable ExtractContext (timeout-aware q + fact/edge/diagnostic buffers + the satellite/provenance/owner push helpers) defined in scope.ts. Call order is preserved 1:1, so the resulting fact / edge / diagnostic ordering is byte-identical to the pre-split extractor. rules.ts: keeps the types, KNOWN_PARAMS, rulesFor, and the single RULES registry — now composed from 14 per-family KindRules records under rules/. Shared rendering/metadata helpers (including the now-exported ROLE_FLAGS) live in rules/helpers.ts. Family files import the registry types type-only, so the runtime import graph (rules -> family -> helpers -> render) carries no cycle. Public surface unchanged: extract / ExtractResult / ExtractionTimeoutError / pruneOrphanedSatellites from extract.ts, and RULES / rulesFor / ActionSpec / KNOWN_PARAMS / PlanParams / AttributeRule / FactView / KindRules from rules.ts. Validation: corpus 420/420 (PGDELTA_TEST_IMAGE=postgres:17-alpine), the extract-output pin tests (extract, depend-edges-oracle, diagnostic-noise, owner-edge, statement-timeout) 25/25, plus check-types + format-and-lint + knip all clean.

charset=UTF-8 Content-Transfer-Encoding: 8bit Extend the pg-delta-next test matrix to the full set of supported PostgreSQL versions (14, 15, 16, 17, 18) so the engine tracks PostgreSQL's own support window. - CI (`.github/workflows/pg-delta-next.yml`): add 14 and 16 to both the `test` and `corpus` version matrices. - dummy_seclabel build (`tests/containers.ts`): map 14 -> alpine 3.19 (postgresql14-dev 14.17) and 16 -> alpine 3.23 (postgresql16-dev 16.14), reusing Alpine bases already in the map (no new base images). - Extractor PG14 compatibility (`src/extract/publications.ts`): publication column lists (`pg_publication_rel.prattrs`), row filters (`pr.prqual`), and schema membership (`pg_publication_namespace`) are PG15+. The publications query now detects `server_version_num` and, on PG14, degrades to bare table membership — exactly the publication feature set PG14 has. The PG15+ query is semantically unchanged. - Corpus: tag the 4 scenarios whose DDL needs PG15+ features with `meta.minVersion: 15` (publication column lists / row filters, `disable_on_error`, `security_invoker`); the engine harness already skips scenarios below their `minVersion`. - Test fixtures: `extract.test.ts` and `depend-edges-oracle.test.ts` created a publication with a PG15+ column list in setup. They now issue the column list only on PG15+ and gate the column-list assertions accordingly. The depend-edges oracle additionally excludes pg_depend rows that legitimately differ across the matrix (object self-dependencies — PG14 records view/matview _RETURN self-deps, PG15+ does not — and `public` schema ownership, owned by the bootstrap role on PG14 vs pg_database_owner on PG15+), pinning the PG15+ publication column-list edges in a separate gated check. Validation (RED before the extractor fix: the PG14 corpus failed 410/420, every scenario hitting `column pr.prattrs does not exist`): - Corpus 420/420 on postgres:14/15/16/17/18-alpine. - dummy_seclabel proof green on postgres:14 and 16 (exercises the new map). - Non-corpus integration suite green on PG14 (345 pass) except 5 pre-existing failures (proof x2, renames x3) that also fail on PG17 and at the pre-refactor parent — addressed separately. (pg-delta-next is private/unpublished, so no changeset.)

A genuinely changed owner across a rename still emits its OWNER TO. Gated behind acceptedRenames, so the default renames: "off" path — and the whole corpus — is byte-for-byte unchanged.

The integration assertions in proof.test.ts still expected the old dotted "app.t" and had been failing on every PG version (and at the pre-refactor parent); the passing unit test (prove.test.ts) already demonstrates that `.table` is the map key. Update the two assertions to the relKey tuple. No production change — prove.ts already produces the relKey by design.

That internal string leaked onto the verdict's public surface: the CLI `prove` command printed `["app","t"]` to users verbatim. Change `.table` (dataViolations, rewriteViolations, coverage.perTable, coverage.tablesSkipped) to a structured `TableRef { schema, name }`: - detectViolations keeps the relKey for its collision-free map lookups (recreatedTables / declaredRewriteTables) but parses it (via the existing parseRelKey) into { schema, name } for the verdict — unambiguous, parse-free for consumers, consistent with the codebase's structured identities. - Consumers render with render.ts `rel()`: the CLI `prove` command and the corpus proof-failure diagnostics now show a properly-quoted `app.t` instead of a JSON tuple. - relKey is exported so the pure-logic unit test (prove.test.ts) feeds realistic relKey-keyed maps instead of dotted fakes. `verdict.ok` is derived purely from violation counts, so behaviour is unchanged.

P1 #2 — loadSqlFiles returned partial state on maxRounds exhaustion. The retry loop `break`d when the round budget ran out, then fell through to extraction, so a caller could receive a fact base missing files that never converged. It now throws ShadowLoadError naming the still-pending files and their last failures; the budget is checked before incrementing so the success-path `rounds` count is unchanged. RED: expect(error).toBeInstanceOf(ShadowLoadError) -> Received: undefined P1 #3 — foreign-table relation-level dependencies were dropped. The set-based pg_depend resolver's `rel` CTE never mapped pg_class.relkind 'f', so relation-level foreign-table endpoints resolved to NULL and the edge was discarded (column-level edges already worked via the `col` CTE). Added `WHEN 'f' THEN 'foreignTable'` and 'f' to the relkind filter. RED: expect(depends).toContain("view:ftapp.v_count -> foreignTable:ftapp.ft") -> edge absent from resolved set P1 #1 — filtered child facts leaked through create-rule inlining. Action emission passed full `desired` to rules, so create/recreate/in-place-alter rules inlined children (alsoProduces) whose own add delta was policy-filtered. Emission now renders against the projected plan target (projectedDesired) while buildActionGraph keeps the un-projected `desired` for the missing-requirement invariant — the two clearly named views the review asked for. Covers all four alsoProduces shapes (column DEFAULT, partition columns, composite type attributes, publication relations). RED: expect(action.sql).toBe('... ADD COLUMN "x" integer') -> Received: '... ADD COLUMN "x" integer DEFAULT 42' Docs: rewrote tier-3 §1 to the two-views conclusion (the invariant is necessary-but-not-sufficient; emission uses the projected target), marked the extractor/rule split (items 4/5) shipped, and repointed onboarding at the per-family extractor/rule files. Archived the follow-up review. No changeset: @supabase/pg-delta-next is private (0.0.0) and excluded from the release set, matching the rest of this branch.

The expected result should be + either: + - `ALTER TABLE ... ADD COLUMN "x" integer` with no default, or + - a plan-time error if filtering child facts independently is declared invalid. + +Architecture note: + +The planner currently exposes too much of the policy projection as caller +discipline inside one Module.

Three ownership-boundary fixes follow from that, plus a CLI diagnostic gap. P1 #1 — accepted rename + owner change dropped the old role too early. The owner link action now carries releases:[oldOwnerId]; the source-side unlink is keyed by the OLD id, which the destination link never looks up, so a dest-id → source-owner StableId map supplies the fallback. The release edge orders ALTER … OWNER TO before DROP ROLE. P1 #2 — table rename + owner-role rename formed a dependency cycle. (a) the carried-owner name is mapped THROUGH accepted role renames, so a table whose owner role is also renamed reads as an unchanged owner → no spurious ALTER … OWNER TO; (b) buildActionGraph takes renameActionIndices and skips `owner` edges for rename actions on both the produces (desired) and destroys (source) sides, so the two renames no longer deadlock. Real create/drop owner ordering is untouched. P1 #3 — default-privilege hygiene scanned unprojected `desired`, emitting an impossible REVOKE for a policy-filtered grantee. It now reads `projectedDesired` (owner edge, defaultPrivilege iteration, acl existence) and skips created facts absent from the projected target. P2 — `pg-delta-next prove` hid rewrite-only failures. Extracted a pure, testable formatProofFailure(verdict) and added the rewrite-violations block, mirroring the corpus runner so a proof failure always names the offending table. RED → GREEN confirmed at unit and integration level (the integration cases failed with `ownerIdx 3 < 2` and the 3-action dependency cycle without the fix). No regressions: 270 src unit tests, owner-edge/renames/proof integration suites, format-and-lint, check-types, knip all clean. No changeset (pg-delta-next is private/unreleased).

Several stable ids embed role NAMES — owner edges, ACL grantees, memberships, user mappings, default privileges — so a diff across a role rename surfaces them as remove/add (or owner unlink/link) pairs differing only by the renamed name. The previous fix only carried ownership when the OWNED OBJECT was also renamed; a role-only rename on a stable object still emitted a spurious ALTER … OWNER TO, which either cycled with the role rename or falsely failed the capability check. Introduce one Depth Module — role-rename-carry.ts — that answers "does an accepted role rename carry this delta?" in a single place: - relabelRoleNames(id, map): remap every role name a stable id embeds (recursing into comment/acl/securityLabel targets). - computeRoleRenameCarry(deltas, map): the remove/add fact pairs and owner unlink/link pairs the rename carries — a pair is carried only when the relabeled id matches AND the payload is identical (a content change still needs its own DDL). plan() now builds the role-rename map once after rename detection, cancels carried fact deltas from the worklists, and skips carried owner links in the owner-edge loop BEFORE the capability check (so there is no phantom owner action to authorize). The owner-edge cycle and false capability failure are gone; ACL/membership/userMapping/default-privilege churn is gone too. The carry is a strict no-op when no role rename is accepted (the guard returns early), so the corpus path — which plans with renames:off — is unchanged. P3: the isolatedClusterPair() header no longer claims automatic role cleanup; it documents that roles are cluster-global, accumulate, and that cluster-level tests isolate by distinctive role names/configs + proving against the sacrificial source directly. RED → GREEN confirmed at unit and integration level (without the fix: the 2-action cycle and "DEFAULT PRIVILEGES … Received 2" churn). No regressions: 287 src unit tests, owner-edge (8) + renames (9) integration, format-and-lint, check-types, knip all clean. No changeset (pg-delta-next is private/unreleased).

But it is not technically optimal: + +- it does unnecessary DDL; +- it may require privileges that a pure role rename would not require; +- it spreads "role rename carries this by OID" knowledge across ad hoc planner + branches instead of one deep Module. + +### Suggested direction + +Introduce a single planner Module, or at least a local helper, that answers: + +```text +Does this delta represent a role-name-bearing fact that PostgreSQL carries +through an accepted role rename? +``` + +That Module's Interface should probably be data-shaped: + +- input: accepted role rename map plus a delta/fact/edge id; +- output: carry / do not carry, and the corresponding source/destination ids. + +Then the planner can cancel or skip carried role-name-bearing deltas in one +place, improving locality. Owner-edge carry would be one adapter/use case; ACL, +membership, and default privileges could be added incrementally. + +This is a Depth opportunity: the caller should not need to know every role-name +field across the stable-id union. That knowledge belongs behind one seam. + +## P3 - isolated cluster pair comments overstate role cleanup + +**File** + +- `packages/pg-delta-next/tests/containers.ts:3` + +### What happens + +The test-container header says: + +```text +one shared PostgreSQL cluster ... plus a lazily started PAIR of clusters for +scenarios whose point is cluster-level state (roles/memberships/default +privileges) - those run state A and state B on different clusters, with role +cleanup between scenarios. +``` + +But `isolatedClusterPair()` is a singleton pair: + +```ts +let isolatedPair: Promise<[Cluster, Cluster]> | null = null; +export async function isolatedClusterPair(): Promise<[Cluster, Cluster]> { + isolatedPair ??= Promise.all([startCluster(), startCluster()]); + return isolatedPair; +} +``` + +The helper exposes `dropRolesExcept`, but it is not called automatically. The +new owner-edge integration tests use distinctive role names/configs, so this is +not an immediate flake in the implementation I reviewed. Still, future tests may +read that comment and assume automatic cluster-role cleanup exists. + +### Suggested fix + +Either: + +- update the comment to say role cleanup is the caller's responsibility; or +- add a role-cleanup wrapper for cluster-level tests and make those tests use it. + +For test locality, the second option is better if more role-heavy tests are +coming. The test's Interface should not require every caller to remember the +cluster-global role lifecycle. + +## Note on clone-based role regressions + +The other agent's warning is correct: + +> A clone-based regression for owner role drops can falsely fail because roles +> are cluster-global, and the original source database can keep the old role +> pinned after cloning. + +For plans that drop or rename roles, applying/proving directly against a +sacrificial source database is the right pattern. The new `owner-edge.test.ts` +comments document this well, and the integration tests follow the same style as +`renames.test.ts`. + +## What looked good + +- The owner-change-under-table-rename fix now gives the owner action + `releases: [oldRole]`, which orders it before old-role drop. +- The table rename + owner-role rename fix is covered by both a no-Docker unit + test and a Docker integration test. +- Default-privilege hygiene now uses `projectedDesired`, matching the emission + seam used by create/recreate/in-place alter rendering. +- `formatProofFailure` is a good small Module.

The previous carry only handled identical payloads; a payload change under a role rename fell back to old-name teardown + new-name create (extra DDL, REVOKE … CASCADE, transient privilege churn). Model it instead as identity carry + post-rename mutation (review P2, fourth follow-up). - computeRoleRenameCarry now returns `changedFacts` ({from,to}) for pairs whose relabeled id matches but payload differs, alongside the existing exact `carriedFactKeys`. - plan() cancels both the old-name remove and the new-name create for each changed pair and emits the PAYLOAD change against the post-rename id: the in-place alter rule for alter-shaped attrs (membership.admin → GRANT/REVOKE ADMIN OPTION, userMapping.options → ALTER USER MAPPING, comment/securityLabel), or a post-rename drop+create for replace-shaped attrs (acl, defaultPrivilege). Every emitted action consumes the renamed role(s) the new id references, so it orders AFTER the role rename; the carried fact id itself is NOT consumed (it is neither in source nor produced, so buildActionGraph would flag it missing). P3a — guard the Module against future role-bearing kinds: stable-id.ts exports `ALL_FACT_KINDS` with a compile-time completeness check, and role-rename-carry.ts exports `ROLE_NAME_BEARING_KINDS`; a test partitions the full inventory so a new `StableId.kind` must be triaged rather than slip through relabelRoleNames' default. P3b — live integration coverage: a role rename carrying acl + membership + user mapping unchanged, and a payload-changing user-mapping proof (ALTER USER MAPPING, no drop/create), both proven against the sacrificial source. RED → GREEN confirmed at unit and integration level (without the fix: the membership REVOKE … CASCADE churn and the DROP/CREATE USER MAPPING churn). The carry is a strict no-op without an accepted role rename, so the corpus (renames:off) is unchanged. No regressions: 297 src unit tests, owner-edge (10) + renames (9) integration, format-and-lint, check-types, knip all clean. No changeset (pg-delta-next is private/unreleased).

If replacement is still the selected rule shape, run the target-side replacement only after the role rename. +- `defaultPrivilege.privileges` / `defaultPrivilege.grantable`: same idea as ACLs: replace against the post-rename role id, not both old and new names. + +I would extend `computeRoleRenameCarry` into a slightly deeper planning Interface: + +- exact payload match -> current `carriedFactKeys`; +- relabeled id match with payload difference -> a `changedRoleRenameFacts` pair `{ from, to }`; +- the planner consumes that pair by removing the old-name `remove` delta and scheduling a target-id payload mutation after the role rename. + +That keeps the good part of this change, namely one role-rename carry Seam, while giving it enough Depth to model identity carry and payload mutation separately. + +Why this matters: + +- fewer DDL statements; +- lower lock and privilege footprint; +- less transient privilege churn; +- avoids `REVOKE ...

The remaining gap is that the carry Module now owns more catalog families than the live proof exercises. + +I would add one compact integration test that creates a source/destination pair with an accepted role rename and at least: + +- table ACL granted to the renamed role; +- role membership involving the renamed role; +- user mapping for the renamed role, if `postgres_fdw` is available in the test image. + +The assertion should be the same shape as the default-privilege test: + +- `ALTER ROLE ...

The drop is then a redundant idempotent statement — and this is GENERAL to every ACL privilege change, independent of role renames. So prettify it in the cosmetic compaction pass (correctness first, prettify later) rather than special-casing per kind in the planner (which would both violate the no-kind-names guardrail and miss the normal ACL-replace path). elideRedundantDrops removes a `drop` D destroying a single id I when a `create` P re-produces I with the SAME sql and removing D cannot lose an ordering edge — verified with LOCAL checks (no graph walk), which exhaust the edge kinds that point INTO a drop: - D.consumes ⊆ P.consumes → every producer that had to precede D also precedes P (which remains), so P inherits D's predecessors; - nothing `releases` I → no release edge ordered before D's destroy; - I has no children → no child-teardown ordered before D. Byte-identical sql means P reproduces D's exact effect. It fires only for acl today (the sole self-resetting create); defaultPrivilege's GRANT-only create is not identical to its drop, so its drop is correctly kept. Wired as a second cosmetic pass after compactColumnFolds, gated on compact !== false, so an uncompacted plan keeps the correct-but-verbose shape. RED → GREEN: an ACL privilege change now emits one REVOKE compacted, two uncompacted. New integration test proves the elided plan applies with the SAME clean proof as the uncompacted one (cosmetic by contract). No regressions: 299 src unit tests, compaction/proof/owner-edge/renames/policy integration, format-and-lint, check-types, knip all clean. No changeset (pg-delta-next is private/unreleased).

Presets: supabaseProfile, rawProfile. - apply() gains a reextract option mirroring prove(), so its fingerprint gate re-extracts handler-aware (resolveProfile supplies it); a managed plan no longer reads operational children on the real target as drift. - Public surface (P1 review finding): root re-exports the headline profile API; new ./integrations subpath exposes the full surface (resolveProfile, presets, probeApplierCapability, pgPartmanHandler, SUPABASE_EXTENSION_HANDLERS, the ExtensionHandler contract) so the advertised safety model is assemblable from stable imports. JSDoc updated to point at it. RED: integrations/profile.test.ts failed to import (module missing); public- api.test.ts likewise. GREEN after adding the module + exports (4 + 3 tests).

Adds --profile to all three commands via one shared resolver (src/cli/profile.ts). --profile supabase composes handler-aware extraction, the Supabase policy, baseline resolution, applier capability (--restrict-to-applier), proof re-extraction, and apply fingerprint reconstruction — one flag, not a hand-built recipe. raw stays the default. plan now routes capability through the profile (dropping the ad-hoc probeApplierCapability call); apply/prove thread ctx.applyOptions/proveOptions so the gate + proof reconstruct the SAME managed view the plan diffed. Covered by src/cli/profile.test.ts (raw/supabase/unknown→UsageError); the end-to-end 'plan --profile supabase drops no partman child' lands in the integration suite.

A plan made with --profile supabase handed to bare apply/prove resolved the raw profile and failed only indirectly (gate/drift). - Plan gains profile?: { id }; PlanOptions gains profile?; plan() inlines it like policy/capability. resolveProfile stamps planOptions.profile = { id }, so every CLI-produced artifact records its profile (round-trips via serializePlan). - CLI apply/prove infer the profile from the artifact when --profile is omitted, and reject a contradicting --profile up front (exit 2, before opening a connection) via effectiveProfileId(). Legacy/library artifacts with no profile field still resolve to raw. RED: integrations/profile.test.ts 'planOptions carries the profile id' (undefined vs {id:supabase}); cli/profile.test.ts effectiveProfileId export missing. GREEN after the change. Also: artifact round-trip + legacy-parse unit tests, and a CLI e2e test (plan stamps {id:raw}; apply --profile supabase → exit 2, 'does not match the plan's profile').

Role config was emitted only by the `config` set-delta alter, which never fires when a role is created from empty — so the created role silently lost its `ALTER ROLE ... SET` settings. The role create rule now returns CREATE ROLE … WITH followed by one `ALTER ROLE … SET key TO 'value'` per desired config entry (extracted helper roleConfigSetSql, shared with the config alter branch).

Every pg_seclabel/pg_shseclabel row is user state (the catalogs are empty until SECURITY LABEL runs), so an unresolved row is a real managed-view gap, not a built-in. --strict-coverage escalates it to a hard stop. - COVERAGE.md now distinguishes supported / diagnosed / not-addressable targets.

Mirrors the `plan` command's wiring. - `loadSqlFiles` accepts an optional `extract` callback (default = raw core extract); `schema apply` passes the profile extractor so the shadow desired state is projected with the SAME handlers as the target. GREEN: tests/cli.test.ts "schema profile-awareness" (export --profile raw identity; apply --profile raw --restrict-to-applier) passes; new load-sql-files.test.ts case proves the extract callback is honored; existing cli/export/profile-e2e-partman suites still pass.

The emission block — rename actions, creates (parents first), default-privilege hygiene, drops, replaces, in-place alters, role-rename changed-pair mutations, and owner-edge ALTERs — becomes `emitActions` in src/plan/phases/action-emitter.ts, carrying its own producer/destroyer/fold bookkeeping (the cohesive sub-algorithm stays together, now behind a named boundary). It enforces a create-produces-its-fact invariant at the phase boundary: every worklist add must be materialized by a producing action (the structural floor of "a create materializes the desired fact"; full per-kind payload materialization, e.g. role GUC config, is each rule's contract). plan() is now a ~240-line orchestrator: buildChangeSet -> expandReplacements -> emitActions -> finalizeActions -> assemble artifact. Behavior-preserving: full PG17 corpus 424 pass (identical to baseline); src/ unit suite 323 pass.

Captures the problem, the +correctness tension we discovered, and the alternatives with trade-offs so +implementation can pick a path later. + +Scope note: the related **progress-based shadow-load round cap** (a separate, +self-contained fix) IS implemented — `loadSqlFiles` now scales `maxRounds` with +file count (`Math.max(files.length + 1, 25)`) so a deep dependency chain that is +making progress never hits an artificial ceiling. This doc is only about +auto-provisioning the shadow database itself. + +## Problem + +`schema apply` materializes the declarative `.sql` files into a **shadow** +database, extracts it, and diffs against the target (parser-free design — +"Postgres is the elaborator", see `packages/pg-delta-next/src/frontends/load-sql-files.ts`). +Today `--shadow ` is **required**, so the operator must provision and +manage a second empty Postgres database. That is the single biggest DX friction +in the declarative flow. Goal: make `--shadow` optional by auto-provisioning a +throwaway shadow, while staying **safe** and **correct**. + +## The correctness tension we found (the crux) + +A naive auto-shadow on the **target's own cluster** (a sibling temp database) is +**unsafe**: cluster-global DDL (`CREATE ROLE`, role `GRANT`s, `ALTER DEFAULT +PRIVILEGES`, `TABLESPACE`) isn't database-scoped, and the loader commits +per-file, so such statements **commit against the real target cluster** before +any leak check — and `ALTER ROLE … SET` on a pre-existing role can't be undone. +→ Rejected. + +An **isolated** shadow (its own cluster, e.g. a Docker container) is safe, but +introduces a **correctness** problem: it has its *own* cluster-global roles +(`postgres`, `pg_*`) that differ from the target's (`test`, app roles, `pg_*`). +Extraction includes role/membership/default-privilege facts, so diffing the +shadow against the target produces **spurious and dangerous** role changes +(drop the target's roles, recreate the shadow's, churn ownership) even when the +declarative files never mention roles. + +Root cause: the existing same-cluster `--shadow` flow is correct for roles only +**by accident** — roles are cluster-global and therefore visible identically +from any database on the same cluster, so they cancel in the diff. The tool has +an implicit assumption that **shadow and target share a cluster**. Any isolated +auto-shadow breaks that assumption. (This latent issue also affects a +user-supplied `--shadow` on a *different* cluster; isolation just forces it into +the open.) + +Conclusion: declarative **schema** (database-local) and cluster-global +**roles/grants** are two problems with different correctness models. An +auto-shadow naturally serves the former; the latter needs the target's cluster +context. + +## Airtight, parser-free detection of cluster-global intent + +An isolated container starts **pristine**, which gives a clean primitive: snapshot +its cluster-global catalog (`pg_roles`/`pg_auth_members`/`pg_db_role_setting`/…) +**before** loading the files and **after**. The delta is exactly what the files +declared for cluster-global state — DO-blocks, dynamic SQL, anything — because +it's the *real post-load catalog*, not a text scan. This is consistent with +"Postgres is the elaborator" and is safe (it's inside the throwaway container). +Used either to **refuse** (option B) or as the **baseline** input (option C). + +## Alternatives + +### A. Sibling temp DB on the target's cluster — REJECTED +Correct for roles (shared cluster) but unsafe: cluster-global DDL in the files +leaks/commits onto the target before detection. Not viable. + +### B. Isolated Docker container + scope cluster-global OUT of the diff +- Container = dedicated cluster ⇒ fully safe. Image `postgres:-alpine` + ⇒ version-correct extraction. +- Filter `role` / `membership` / `defaultPrivilege` (and other cluster-global) + facts out of both sides before diffing, so the bootstrap-role mismatch never + surfaces. Owner edges to scoped-out roles prune ⇒ objects created + applier-owned (no spurious `ALTER … OWNER`). +- Use the before/after snapshot to **refuse loudly** if the files manage + cluster-global state ("auto-shadow manages database-local schema only — use + `--shadow` on a cluster matching the target for roles"). +- **Pro:** simplest correct option. **Con:** auto-shadow can't manage roles at + all (not even add). + +### C. Isolated Docker container + BASELINE subtraction — RECOMMENDED +Reuse `subtractBaseline` (`packages/pg-delta-next/src/policy/baseline.ts`), which +drops facts present-and-identical (same id + payload hash) in a baseline +`FactBase` from **both** sides before diffing (`resolveView`, +`packages/pg-delta-next/src/policy/policy.ts`). + +Baseline = **(shadow container's pristine cluster-global state) ∪ (the target's +current cluster-global state)**, passed as `PlanOptions.baseline`: +- shadow bootstrap roles (`postgres`, …) are in the baseline ⇒ **not** created on + the target; +- the target's existing roles are in the baseline ⇒ **not** dropped; +- owner edges to baselined roles prune ⇒ objects created applier-owned (no owner + churn); +- a role the files genuinely **declare** is in neither baseline ⇒ survives in + desired ⇒ `CREATE`d. ✓ +- **Limitation (intrinsic to subtraction):** *modifying* a pre-existing role's + attributes can't be expressed — subtracting the target's copy makes the changed + role look brand-new (→ `CREATE ROLE` that already exists). Documented contract: + auto-shadow can add roles and leaves undeclared roles alone, but to **alter** a + pre-existing role use `--shadow` on a matching cluster. +- **Pro:** correct for the realistic cases (add / leave-undeclared / owners / + db-local schema), reuses existing machinery, one narrow documented limit. + **Con:** must construct the union baseline `FactBase` from filtered extractions. + +### D. Isolated Docker container + SEED target roles into the shadow +Replicate the target's roles/memberships/configs into the container *before* +loading the files (a mini-apply of the target's cluster-global facts via the +existing role rules). The shadow then holds `role@target-value` + the files' +changes, so the diff yields clean `ALTER` (modify), `CREATE` (add), and no drop +of undeclared roles (they're present on both sides → additive semantics). +- **Pro:** full declarative role fidelity, no limitation. **Con:** materially + more code + edge cases (superuser-name/owner alignment so the load owns objects + as the target's applier; membership/config replication; the "additive vs + authoritative" choice for undeclared roles). + +### E. Park — keep `--shadow` required +Ship nothing here; the round-cap fix already landed. Lowest effort. + +## Recommendation + +**Option C (baseline)**, with **D** as a later upgrade if altering pre-existing +roles via auto-shadow becomes a real requirement.

But that invariant is only comment-level today. + +The `Plan` artifact persists: + +- source and target fingerprints; +- policy; +- applier capability; +- deltas/actions/safety report. + +It does not persist the profile id or handler set that produced the source +fingerprint. Meanwhile `apply` and `prove` default to the `raw` profile when +`--profile` is omitted. A plan produced with `--profile supabase` can therefore +be handed to: + +```bash +pg-delta-next apply --plan plan.json --target ... +pg-delta-next prove --plan plan.json --clone ... --desired-snapshot ... +``` + +and those commands will resolve the raw profile, not the Supabase profile. + +This likely fails safely for the known pg_partman case: the fingerprint gate or +proof drift should see operational children reappear and reject the run. But the +error is indirect, and the Interface still relies on the operator remembering to +repeat the profile exactly. + +#### Suggested fix + +Stamp the plan artifact with the selected profile id when the CLI uses a known +profile. + +Possible shape: + +```ts +interface Plan { + // ... + profile?: { id: string }; +} +``` + +Then make CLI `apply` and `prove` behave as follows: + +- if `--profile` is omitted and `plan.profile?.id` exists, use that profile; +- if both are present and differ, fail before opening the apply/proof path; +- if the profile id is unknown to this binary, fail with a direct message; +- keep raw/no-profile behavior available for library-produced artifacts. + +This turns the current comment-level contract into an artifact-level Interface. +The leverage is high: one small field prevents every future profile command from +having to rediscover mismatches through drift or fingerprint failure. + +Suggested tests: + +- serialize/parse round-trips `profile.id`; +- CLI profile resolver defaults to the artifact profile when `--profile` is + omitted; +- CLI rejects `plan.profile.id = "supabase"` with `--profile raw`; +- apply/prove still allow legacy artifacts without a profile field. + +### P3: Phase B roadmap docs still describe removed helper Interfaces + +References: + +- `docs/roadmap/extension-intent-phase-b.md:24` +- `docs/roadmap/extension-intent-phase-b.md:27` +- `docs/roadmap/extension-intent-phase-b.md:74` +- `docs/roadmap/tier-1-extension-intent-phase-b.md:26` +- `docs/roadmap/tier-1-extension-intent-phase-b.md:30` +- `docs/roadmap/tier-1-extension-intent-phase-b.md:58` + +The canonical architecture docs were refreshed, but the Phase B roadmap still +names the pre-profile substrate: + +- `excludeManaged(factBase)` as the main subtraction path; +- `ExtensionHandler` + `extractWithHandlers` + `extractManaged`; +- proof re-capture via `extractManaged`. + +The implementation intentionally removed that recipe.

Extract — a database becomes facts + +`extract()` reads a database in **one consistent snapshot** (a single +`REPEATABLE READ` transaction, so the catalog can't shift under it) and produces +a **fact base**. A *fact* is one addressable thing — a table, a column, a +constraint, an index, a policy, an ACL grant, an ownership edge — captured as a +content-addressed `{ id, payload }`. Identity is structured (schema + name + +kind), never a fragile attnum or OID. DDL text is whatever +PostgreSQL's own `pg_get_*def()` reports, so it's already canonical. + +The fact base is a Merkle tree: every fact has a hash, and parents roll up their +children's hashes. That makes comparison and change-detection cheap. + +### 2. Diff — two fact bases become deltas + +Because everything is a fact at the same grain, `diff()` is **generic** — a +single descent that compares hashes and emits `add` / `remove` / `set` / `link` / +`unlink` deltas. There is *zero per-object-type code* in the diff. A new kind of +object adds no `if` here. + +### 3. Plan — deltas become ordered actions + +`plan()` turns each delta into an atomic **action** (a `CREATE` / `ALTER` / +`DROP`) using a **rule table** — data, not a hundred hand-written change classes. +It then builds **one dependency graph** mixing all the edges and runs **one +deterministic topological sort**. + +The payoff of working at fact grain: **dependency cycles structurally cannot +form**, so there are no cycle-breakers, no repair loop, no second-pass +normalization — the things that made the old ordering code fragile simply don't +exist here. + +### 4. Prove — a plan earns trust on a clone + +This is the safety net the old engine never had. `provePlan()` applies the plan +to a **throwaway clone**, re-extracts it, and checks two things: + +- **State proof** — the result's fact hashes equal the desired state (zero drift). +- **Data preservation** — rows in kept tables survive (and a table rewritten + without declaring it fails the proof). + +Because re-extraction yields the same kind of facts, "did the migration work?" +becomes a hash comparison, run automatically in CI — not a production incident. + +### 5. Apply — run it for real + +`apply()` executes the plan against the target in lock-aware **segments** +(grouping transactional actions, isolating ones that can't run in a transaction +like `CREATE INDEX CONCURRENTLY`). It re-extracts the target first and refuses to +run if the target drifted from what the plan was built against (the +**fingerprint gate**). + +--- + +## The two cross-cutting ideas + +Two concerns don't belong to any single step — they shape the whole pipeline: + +### The managed view — "what do we even manage?" + +Real databases contain things you don't own: platform-managed roles and schemas, +objects created by an extension, operations your applier role can't perform. +Rather than scatter `skipSchema` / `skipAuthorization` flags through the code, +the engine projects a **managed view** of the fact base — once — and applies it +**identically before planning and before proving**.

That is why it is safe to pause here and treat 4b as a dedicated -migration rather than a tail-end cleanup. - -## Guiding principle - -The review's thesis is correct and is the organizing idea of this plan: **the -core diff/planner machinery is sound; the risk is safety semantics becoming -implicit at the boundaries** — extraction policy, proof coverage, frontend -loading. Every item below makes one boundary *explicit and auditable*. - -A note on what already converges: Phase A's `excludeManaged` -(`src/policy/managed.ts`) is a **fact-level** transform applied symmetrically to -source/desired/proof — chosen precisely because delta-level filtering drifts the -proof. That is the same conclusion the review reaches in finding #2. So Phase A -is not rework; it becomes one input to the projection layer (Item 1). - ---- - -## Work items - -Each item: the problem (with the review finding # and my verdict), the fix -*within the architecture*, files, tests/gates, dependencies, and effort/risk. -All work follows repo discipline: RED→GREEN, no SQL-byte assertions -(guardrail 6), corpus + differential gates, `private:true` so no changeset. - -### Item 1 — Explicit projection + projected target fingerprint (review #2, **strong agree**) - -**Problem.** `filterDeltas` removes deltas, but the plan's target fingerprint is -the *full, unprojected* `desired`. `provePlan` then diffs the clone against full -`desired` with no policy, so a policy-hidden delta makes the plan intentionally -not converge while the metadata still claims the unprojected target. Ambiguous -target = both a correctness risk and an explainability gap. - -**Fix (within §3.9 "baselines = fact-base subtraction; policy decides -visibility").** Introduce an explicit projection step that produces the state -the plan *actually targets*, and fingerprint/prove against that: - -```ts -interface Projection { - projectedSource: FactBase; - projectedDesired: FactBase; // == the honest plan target - ledger: ProjectionEntry[]; // every fact/delta removed, with reason -} -``` - -Two distinct, clearly-named mechanisms (the review collapses them; keeping them -separate is what makes the semantics crisp): - -- **Projection (fact-level, both sides, affects the fingerprint)** — "out of my - universe." Subtract facts from *both* source and desired so they never diff. - This is the home for: baseline (`subtractBaseline`), managed/operational - objects (`excludeManaged`, Phase A), system schemas/roles, and extension - members (Item 4). The target fingerprint reflects the subtraction. -- **Filtering (delta-level, "I see it, I won't act on this change")** — for - *verb-specific* suppression (the Supabase policy uses `verb` predicates). A - filtered delta MUST be reflected in the target: `projectedDesired` is the - fact base reached by applying only the **kept** deltas to `projectedSource` - (equivalently, `desired` with each filtered fact reverted to its source - value). So `fingerprint(projectedDesired)` is honest and - `diff(proven, projectedDesired) == ∅` is the real proof obligation. - -`plan()` computes `projectedDesired` and uses it for fingerprints; `provePlan` -targets it; both surface the `ledger` so "what was intentionally excluded, and -why" is reportable. - -**Files.** new `src/policy/project.ts` (compose baseline + managed + policy -projection + filtered-delta reversion → `Projection`); `src/plan/plan.ts` -(target fingerprint from `projectedDesired`; expose `ledger`); -`src/proof/prove.ts` (diff against `projectedDesired`); `src/plan/artifact.ts` -(serialize the ledger); public API in `src/index.ts`. - -**Tests/gates.** Unit: a fact-level projection rule removes a fact from both -sides → no delta + fingerprint reflects it; a verb-filtered delta → that fact -reverts to source in `projectedDesired`; the ledger records both with reasons. -Integration: a Supabase-style policy (exclude system schema + filter a `remove`) -→ `provePlan` converges to `projectedDesired`, not full desired. Full corpus -regression. - -**Depends on:** nothing. **Enables:** Items 2, 4b. **Effort/risk:** medium / -medium (touches the plan→prove contract; well-bounded by the proof gate). - -### Item 2 — Proof reports coverage; content fingerprints for seeded tables (review #3, **agree**) - -**Problem.** `provePlan` verifies drift deltas + row **counts** + `relfilenode`. -`autoSeed` is off by default and few scenarios ship `seed.sql`. Row-count -preservation ≠ content preservation (a lossy type change or truncate+reinsert -passes). The README overstates the guarantee. - -**Fix (within §3.7 proven/observed/vetted tiers).** Stop reporting a broad -boolean; report **what was actually checked**: - -```ts -interface ProofCoverage { - tablesChecked: number; tablesSkipped: Array<{ table: string; reason: string }>; - perTable: Array<{ - table: string; - contentMode: "fingerprint" | "count" | "none"; - recreated: boolean; rewriteDeclared: boolean; - rowsBefore: number; rowsAfter: number; - }>; -} -``` - -Add **deterministic content fingerprints** for seeded/non-empty kept tables -(`md5(string_agg(t::text, '\n' ORDER BY t::text))` before vs after) — a content -change on a `dataLoss:"none"` table is a violation, not just a count change. -Keep `autoSeed` opt-in (it is an audit mode), but the coverage report makes -"0 rows checked" honest so the verdict can't be misread. The verdict's `ok` -stays, but is now backed by an auditable coverage object. - -**Files.** `src/proof/prove.ts` (coverage + content fingerprint); README.md + -`API-REVIEW.md` (proof described as tiers + coverage — see Item 8); expand -`seed.sql` for the destructive corpus scenarios that most need content proof. - -**Tests/gates.** RED: a scenario that preserves row count but mutates content -(e.g. a column type change with a lossy `USING`) → today's proof says `ok`; with -content fingerprints it must FAIL. GREEN after the fingerprint check. - -**Depends on:** Item 1 (proof must target `projectedDesired`). **Effort/risk:** -medium / low. - -### Item 3 — Typed policy predicates + edge-kind in `edgeTo` (review #7, **agree, independently confirmed**) - -**Problem.** `idField` is stringly-typed (a typo silently never matches), and -`edgeTo` matches only the edge *target*'s kind/schema — **not** the edge's -`EdgeKind`. The latter is exactly why Phase A's `managedBy` filtering had to be a -fact-level transform instead of a policy rule. - -**Fix (this is literally §3.9: "typed predicates over fact kinds, identities, -provenance edges, and delta verbs").** Add `edgeKind?: EdgeKind` to -`EdgeToPredicate` and match it in `factMatches`. Add per-kind field-name -**validation** in `validatePolicy` (an `idField` naming a field the kind doesn't -have is a config error, not a silent no-match). Prefer typed identity-field -predicates where the kind is known. - -**Files.** `src/policy/policy.ts` (`EdgeToPredicate`, `factMatches`, -`validatePolicy`); `src/policy/policy.test.ts`. - -**Tests/gates.** `edgeTo: { edgeKind: "memberOfExtension" }` matches only those -edges; an `idField` typo throws in `validatePolicy`. **Depends on:** nothing. -**Enables:** Item 4 (provenance filtering as policy). **Effort/risk:** small / -low. *Good early win.* - -### Item 4 — Provenance as edges; filtering as projection (review #1, **agree; it's the documented end-state**) - -**Problem.** Extension-member objects are removed at extraction by -`notExtensionMember` anti-joins. This is the documented v1 stand-in -(`COVERAGE.md`), but it is **inconsistent** — a member object is filtered while -its ACL/comment satellite is not — which is the root of CLI-1471 (orphan `GRANT` -on an extension aggregate). Note: `managedBy` (Phase A) is a *sibling* of -`memberOfExtension`, not the same thing; this item is specifically about -extension **members**. - -**Fix — phased**, because the full flip has a large blast radius (every -extractor query) and a real cost (fact-base inflation): - -- **4a — extraction consistency (small, immediate correctness).** A satellite - (acl/comment/securityLabel) of a filtered object must itself be filtered. - Kills the orphan-satellite bug class (CLI-1471) now, independent of the flip. - Add a corpus scenario for the extension-member-aggregate GRANT. -- **4b — provenance edges (large, the north-star end-state, §3.1 "provenance is - data, an edge fact, not an extraction-time filter").** Stop anti-joining - members; extract them WITH `memberOfExtension` edges to the extension fact. - Projection (Item 1) + an edge-kind policy rule (Item 3) then excludes them. - This is the "observe everything, project intentionally" pillar. - -**Files.** 4a: `src/extract/extract.ts` (satellite emission gated on target -presence) — or rely on the existing missing-requirement guard and assert it. -4b: `src/extract/extract.ts` (remove `notExtensionMember`, emit -`memberOfExtension` edges across all extractor queries); `src/policy/supabase.ts` -(projection rule for `memberOfExtension`); `COVERAGE.md`. - -**Tests/gates.** 4a: CLI-1471 scenario — the aggregate's ACL is excluded with -its extension-member target; no orphan GRANT. 4b: extension-member objects -appear as facts with `memberOfExtension` edges; Supabase projection removes -them; full corpus + differential regression (this changes what enters the fact -base, so the differential oracle is the safety net). **Depends on:** Item 1 + -Item 3 (for 4b). **Effort/risk:** 4a small/low; **4b large/high** — recommend -landing 4a immediately and scheduling 4b as its own gated effort (it may even -be staged per extractor family). - -> **4a is shipped (`e605f83`). 4b is shipped for the common member-ROOT -> families** (schemas, tables, sequences, views/matviews, routines, aggregates, -> domains, enum/composite/range types, collations) — each observed with a -> `memberOfExtension` edge and projected out by default, verified by the -> `extension-member-parity` oracle. **Still filtered (documented, deferred):** -> sub-entity families (columns, constraints, indexes, triggers, policies, -> rewrite rules) and rare member-root kinds (FDW, server, foreign table, event -> trigger, publication) keep their `notExtensionMember` anti-joins — a -> regression-free limitation tracked in `COVERAGE.md` and -> `docs/remaining-work/tier-4-deferrals.md`. The 4b migration plan lives in its -> own section below ("Item 4b — dedicated migration plan"). - -### Item 5 — `commitBoundaryAfter` becomes an unconditional segment boundary (review #6, **agree the concern; refine the fix**) - -**Problem.** `plan.ts:727` inserts the boundary "before the FIRST graph -successor" of a `commitBoundaryAfter` action. An `ALTER TYPE … ADD VALUE` is an -in-place `set` that *consumes* the type fact; a same-plan consumer of the new -value (e.g. a new column `DEFAULT 'newval'::myenum`) *also* consumes the type — -they are **siblings with no edge between them**, so the consumer may not be a -graph successor → no boundary → both land in one segment → `55P04`. - -**Fix.** The review's first option ("model enum labels as facts") **does not -help** — `pg_depend` never records per-label dependencies (everything points at -the type), so no finer edge would ever exist; this is not a granularity-is-one -violation. The correct, cheap fix is the review's second option: in -`segmentActions` (`apply.ts`), treat `commitBoundaryAfter` as an -**unconditional** close-the-current-segment boundary *after* the action, -independent of graph-successor shape. Simplify/remove the successor-search -boundary logic in `plan.ts`. Cost: at most one extra segment. - -**Files.** `src/apply/apply.ts` (`segmentActions`); `src/plan/plan.ts` (drop the -conditional boundary insertion); a new corpus scenario: a new enum value used by -a **new column default in the same plan**. - -**Tests/gates.** RED: the new corpus scenario fails under proof (or apply) today -if the consumer shares the segment; GREEN with the unconditional boundary. -**Depends on:** nothing. **Effort/risk:** small / low. - -### Item 6 — SQL-file shadow loading robustness (review #5, **partially disagree; narrower fix**) - -**Problem (corrected).** The review claims a multi-statement file can *partially* -apply. It mostly cannot: `client.query(file.sql)` uses the **simple** protocol, -which Postgres runs as a **single implicit transaction** — statement 2 failing -rolls statement 1 back, and the whole-file retry is clean. The *real* (narrower) -gaps are files containing **explicit `BEGIN/COMMIT`** (breaks the implicit -atomicity) or **non-transactional statements** (`CREATE INDEX CONCURRENTLY` -*errors* "cannot run inside a transaction block" and can never load). - -**Fix (hardening).** Wrap each file attempt in an explicit transaction/savepoint -and `ROLLBACK` on failure (makes the implicit guarantee explicit and robust to -embedded `COMMIT`). Detect non-transactional statements and either classify the -file with a clear diagnostic or strip/rewrite them — in a throwaway shadow, -`CONCURRENTLY` is pointless, so dropping the keyword is safe and lets such files -load. - -**Files.** `src/frontends/load-sql-files.ts`; loader tests (a mid-file failure -retries cleanly; a `CONCURRENTLY` file is handled, not stuck-forever). -**Depends on:** nothing. **Effort/risk:** small / low. - -### Item 7 — Planner internal module split (review #4, **partial agree; do last**) - -**Problem.** `plan.ts` carries many responsibilities in one module. This is -organization hygiene, **not** a locality violation — per-kind knowledge is -correctly in the rule table (guardrail 3); the planner is the generic machinery. - -**Fix.** Behind the **unchanged** public `plan()` API, extract internal modules -(`TransitionClassifier`, `RenameApplier`, `DependentRebuildExpander`, -`ActionEmitter`, `RequirementChecker`, `PlanGraphBuilder`, `Segmenter`, -`Compactor`, `SafetyReporter`). Pure refactor. - -**Files.** `src/plan/plan.ts` → split. **Tests/gates.** Full corpus + -differential must show **state-equivalent plans** (zero behavior change). -**Depends on:** Items 1, 2, 5, 6 ("after semantics settle"). **Effort/risk:** -medium / medium — defer until the semantic items land so we refactor a stable -target. **Lowest priority.** - -> **NOT started — and explicitly sequenced *after* 4b, not before.** Refactoring -> the planner immediately before the provenance flip would blur whether a corpus -> failure came from the semantic change (4b) or the module movement (7). Do the -> semantic migration first, against the *current* planner module, then split. - -### Item 8 — Docs normalization (continuous) (review #8, **agree**) - -**Fix.** Normalize README / `API-REVIEW.md` / `COVERAGE.md` into three buckets: -**implemented & proven**, **implemented with known simplification**, -**deliberately out of the modeled universe**. `COVERAGE.md` is the source of -truth for exclusions. Fix the README proof overstatement (ties to Item 2). Do -this *as part of* each item above (each item updates the relevant bucket) rather -than as a separate pass. - ---- - -## Item 4b — dedicated migration plan (provenance flip) - -**This is the one remaining substantive item.** It is *not* "remove some -filters." It is a **semantic migration from absence-as-policy to -presence-plus-projection**: extension members stop being invisible (anti-joined -away at extraction) and instead become observed facts that carry a -`memberOfExtension` provenance edge and are *projected out by default*. That -touches **five layers at once** — extraction, dependency resolution, default -planning semantics, proof semantics, and corpus expectations — which is why it -gets its own gated plan rather than a single patch. - -**Acceptance criterion (the contract this migration must satisfy):** - -> *Policy-free behavior remains byte-for-byte compatible by default, while raw -> extraction can observe extension members with complete provenance edges.* - -In other words: with no policy, the corpus and differential stay green -(members are projected out as before); but `extract()` on its own now returns a -fact base where members are present, each with a `memberOfExtension` edge. - -### Why hurrying it is dangerous - -Done sloppily, 4b creates a *worse* class of bug than the one it fixes: objects -become visible but not correctly projected (they leak into plans), or -dependency edges point at the wrong abstraction layer (member fact vs the -extension), changing ordering. "Almost right" looks green until one object -family with satellites leaks through. The differential oracle is the safety net, -but only if we gate **after each family**, not just at the end. - -### The five stages (each independently shippable, each corpus-gated) - -**Stage 0 — default projection first, while extraction still behaves the old -way.** Before observing anything new, add the default projection path -(`excludeExtensionMembers`, keyed on the `memberOfExtension` edge — mirror / -generalize Phase A's `excludeManaged` on `managedBy`) and wire it as a default -in `plan()`/`prove()`. With extraction unchanged this is a **no-op** (there are -no `memberOfExtension` edges yet). **Gate:** full corpus on PG 15 + 17 stays -green. *This proves the new projection path preserves current behavior before -the observed universe expands* — the single most important de-risking step. - -**Stage 1 — parity / inventory harness.** Build a test harness that, for each -extractor family, compares **"objects previously removed by `notExtensionMember`"** -against **"objects now present with `memberOfExtension`."** Any mismatch must be -**explicit and asserted**, not discovered later through corpus drift. This is the -instrument that tells us a family flip is faithful *before* the corpus does. - -**Stage 2 — flip one extractor family at a time.** Remove `notExtensionMember` -and emit `memberOfExtension` edges family-by-family. **Do not move them all in -one patch.** Suggested family order (satellite-bearing families last, since they -are where leaks hide): - -1. schemas -2. tables, columns, constraints, indexes, sequences -3. views, matviews -4. routines (functions/procedures/aggregates), triggers -5. types/domains/collations -6. policies -7. grants / comments / security labels / default privileges (**satellites — last**) - -After **each** family: run the parity harness (Stage 1) + the corpus on PG 15. - -**Stage 3 — change dependency resolution deliberately.** The pg_depend -edge-resolver today collapses a member reference *to the extension fact* — which -was correct under filtered extraction (the member didn't exist as a fact). Once -members are present, resolving to the **member fact** is the correct behavior, -but it exposes **new edges and new ordering**. This needs its own focused tests -(not just corpus): assert that a reference into an extension member now resolves -to the member, and that the resulting plan order is still valid. Land this -*after* the families are flipped (the member facts must exist first). - -**Stage 4 — full gate.** Full corpus on **PG 15 + 17 + the differential** at the -end. This is exactly the kind of work where a single satellite-bearing family -can look green locally and leak in the differential — so the differential is the -final arbiter, not optional. - -### Files (4b) - -- `src/policy/managed.ts` (or a sibling) — `excludeExtensionMembers` projection - keyed on `memberOfExtension`; wire as a default in `src/plan/plan.ts` + - `src/proof/prove.ts`. -- `src/extract/extract.ts` — per family: drop `notExtensionMember`, emit - `memberOfExtension` edges; the edge-resolver change (Stage 3). -- New parity-harness test (Stage 1) under `tests/` or `src/extract/`. -- `src/policy/supabase.ts` — the Supabase data-package projection rule for - `memberOfExtension` (so the Supabase corpus stays green). -- `COVERAGE.md` — move extension members from "removed at extraction" to - "observed, projected by default." - -### Gate summary (4b) - -- Stage 0: corpus PG 15 + 17 green with the no-op default projection. -- Each family: parity harness asserts removed-set == newly-present-set; corpus - PG 15 green. -- Stage 3: focused resolver tests (member-targeted edges + ordering) green. -- Stage 4: **full corpus PG 15 + 17 + differential clean.** -- `bun run format-and-lint:fix && bun run check-types && bun run knip` clean at - every commit. - -### Framing - -Treat 4b as an **architectural feature** ("complete provenance, intentional -projection"), not a cleanup. Its value is the general capability: a user `GRANT` -on `cron.job_run_details` becomes a first-class, policy-manageable fact instead -of being silently invisible. The CLI-1471 *correctness* motivation is already -banked in 4a — so 4b can be scheduled on its own merits, without correctness -pressure. - ---- - -## Sequencing - -``` -Item 3 (typed predicates) ─┐ - ├─▶ Item 4b (provenance flip, large) -Item 1 (projection) ───────┘ - │ - └─▶ Item 2 (proof coverage) - -Item 4a (extraction consistency, CLI-1471) ── independent, quick win -Item 5 (enum boundary) ── independent, cheap -Item 6 (SQL-file robustness) ── independent, cheap -Item 7 (planner split) ── after 1,2,5,6 -Item 8 (docs) ── continuous, folded into each item -``` - -**Recommended order** (✅ = shipped, ⏳ = remaining): - -1. ✅ **Item 1 + Item 2** — the coupled, highest-leverage pair (explicit target + - honest proof).

Everything else is either solved or is -CLI/data work over an existing mechanism (§2–§6). - -### CLI-1555 — declarative sync drops `pg_partman` child partitions ❌ needs design (Deliverable A) -### CLI-1591 — `pg_partman`: stop dropping managed partitions + capture `create_parent` intent ❌ needs design (Deliverable B) - -**Why it is hard, restated for the new model.** A partman child -(`part_test_p20260415`, `part_test_default`) is a real user-schema table that -carries **no** `pg_extension` dependency (so the extract-time `deptype='e'` -filter misses it) and whose `relispartition` flag cannot distinguish it from a -*user-declared* `PARTITION OF` (so a blanket filter would also suppress -intended partition drops — explicitly rejected by the product). The only -authoritative signal is `.part_config`, which is **not** -`pg_catalog` — so per the core's "pg_catalog + own utilities only" rule it -cannot live in `src/core`. - -**Solution within the architecture** (this is exactly what §3.9 + provenance -edges + the policy layer are for — no core change, no parser): - -- **Deliverable A (stop the drops).** Add a *provenance source* to the - **Supabase integration / extract layer** (not core): when `pg_partman` is - installed, resolve its schema dynamically via `pg_extension`/`pg_namespace`, - read `part_config` (+ `part_config_sub`), and emit an **edge fact** - `managedBy(partman)` on every child whose `pg_inherits` parent is registered - there (including `*_default` and premade children). Then a single Supabase - **filter rule** — `{ edgeTo: { … partman … } } → exclude` over `add`/`set`/`remove` - — drops those children from the plan entirely. This is the same shape as the - existing extension-member handling (`supabase.ts` Old-12) and the user-trigger - rule (Rule 3): provenance as data, policy decides visibility. Native - `PARTITION OF` tables carry no such edge, so their intended drops still fire — - closing the #5491 regression by construction. - -- **Deliverable B (rebuild fidelity / `create_parent` intent).** This is the - genuinely unsolved part and it brushes against the permanent **DML - out-of-scope** boundary (§1): a from-scratch rebuild needs the - `create_parent(...)` call (and the intent subset of `part_config`'s ~40 - columns) **replayed**, ordered after the parent table. The architecturally - honest home is a **frontend/policy "intent replay" channel**, *not* the schema - fact base: model partman config as a small set of **intent facts** owned by the - integration, rendered as `create_parent()` / `set_part_config()`-style replay - actions that the one-graph sort orders after the parent. The blocker is **RFC - open question #2** (CLI-1431): on the *declarative* path the desired catalog - won't contain `part_config` rows unless the schema source encodes them — so - this needs the declarative-source representation decided first. Until then, - Deliverable A (no data loss) ships; Deliverable B waits on CLI-1430/1431. - -### CLI-1385 — Extensions diffing / data diffing ⛔ partly out of scope / ❌ partly needs design -The schema-diffing half (managed/extension schemas) is **solved by policy** -(§3). The **data-diffing** half — capturing `cron.schedule(...)`, -`pgmq.create(...)`, vault secrets as *intent* — is **permanently out of scope -for the schema contract** (§1: "Out of scope, permanently: data migrations -(DML)"). It can only re-enter as a *separate, explicitly-additive* intent-replay -channel layered beside the engine (same mechanism sketched for partman -Deliverable B), never inside the trusted diff path. This is a product/RFC -decision, not an engine gap. - -### CLI-1430 — per-extension intent matrix · CLI-1431 — declarative source format for stateful extension state ❌ needs design (research) -These two define the *data and the format* that Deliverable B / data-diffing -need. The architecture supplies the **substrate** (policy predicates, provenance -edges, baseline subtraction, an intent-replay channel) but the **content** — -which `part_config`/`cron.job`/`pgmq` columns are intent vs runtime state, and -how a user expresses that intent in `supabase/schema/` — is net-new design. -Verdict stays research/design; everything they feed into already exists. - -### CLI-1389 — `supa-shadow`: zero-infra `pg_catalog` shadow via PGlite 🟡 deferred by design -§7 explicitly evaluates PGlite and **rules it out of the trusted path today** -("extension and version parity rule it out"). The new engine's honest cost is -"needs a reachable Postgres." `supa-shadow` is a legitimate *future frontend* -(it would slot in beside the live-DB and SQL-file doors of §3.2), but it is -intentionally not in scope for v1 — its diffs would not be extension/version -faithful. Not a gap; a recorded deferral. - -### The "substrate-ready" set (engine done, CLI/data surface remaining) -These need no engine design — only a consumer or a data file: - -- **CLI-1459 / 1460 / 1461 / 1462 / 1463 / 1464 — Risk classification 2.0.** The - engine already emits a **proof-verified** per-action safety report - (`dataLoss`/`rewriteRisk`/`lockClass`, vs the old `risk.ts`'s 3 hardcoded - `data_loss` ops). Phases 1–5 are the *productization* of that report: the v2 - wire format, `HazardKind` stable codes, `--allow-hazards` DSL, GitLab reporter. - The hazard *content* (lossy casts, lock levels, replication, security - regressions) maps directly onto rule-table per-action metadata; lock classes - come from the vetted table (`src/plan/locks.ts`). -- **CLI-1436 — service-migration baseline mechanism.** `baseline.ts` + - `scripts/generate-supabase-baseline.ts` implement fact-base subtraction (§3.9); - what remains is operational — committing the generated snapshot - (`src/policy/baselines/` currently holds only `.gitkeep`) and deciding - generation/refresh/ownership. -- **CLI-1597 / 1598 — rewrite `migration squash` on pg-delta + multi-file output.** - The shadow frontend + plan provide "diff between two shadow states," and the - segmented executor already knows the forced transaction boundaries (§3.8); the - squash command, `migration repair` generation, and multi-file materialization - are CLI work over those plan segments. -- **CLI-1424 — squash only preserves `public`.** The new engine diffs **all** - schemas (no public-only limitation); the limitation was a `pg_dump` artifact - the CLI-1597 rewrite removes. -- **CLI-1169 — regex flag to exclude triggers/indexes.** The real defect - (objects auto-created by user `ddl_command_end` event triggers reappearing in - every diff) is addressable with a **policy predicate**; a regex CLI flag is a - thin consumer over `filterDeltas`. Substrate present. -- **CLI-1006 — schema filtering flag.** The `schema` predicate in the policy DSL - is the engine-level mechanism; the CLI flag is a consumer. -- **CLI-1603 — make `extractDepends` faster.** The new extraction is parallel + - single-snapshot (§3.2); that fixes the *consistency* class of failures, and - the snapshot model removes mid-run aborts, but raw `pg_depend` query latency on - huge DBs is still a tuning concern (statement-timeout budget, index hints). -- **CLI-1582 — `db reset` fails with the local Stripe Sync Engine.** The - engine-side lever is the same as managed-schema handling: treat the - integration-owned (Stripe) schema as an **externally-managed schema** excluded - via a policy baseline/filter, so pg-delta never emits drops or cross-schema FKs - against it. The `db reset` ↔ integration-container *sequencing* is CLI - orchestration, outside the engine. -- **CLI-1607 — typed auth-failure error + credential redaction.** Redaction of - secrets in serialized DDL is **done** (corpus `sensitive-handling--*`); the - typed, 4xx-mappable auth error is a connection/error-surface concern (CLI). -- **CLI-1432 — cross-schema trigger patterns.** Already substantively handled: - `supabase.ts` Rule 3 keeps user triggers on managed-schema tables - (`auth.users → public.profiles`) keyed on the trigger function's schema; the - ticket's remaining value is edge-case research. - ---- - -## 2.

I prioritized the new `packages/pg-delta-next` implementation and the docs that explain its architecture and roadmap. - -## Executive summary - -The rewrite has a strong core shape. The `FactBase` / `StableId` / dependency-edge model is a good deep Interface: it gives the planner, proof loop, corpus runner, and SQL-file frontend a shared vocabulary without forcing each part to understand every catalog detail. The corpus/proof machinery is also a strong choice: it turns "we think this migration is equivalent" into a mechanically checked claim against a real database. - -I did find several correctness issues that should be fixed before treating the branch as complete. The most important one is that policy-filtered planning currently computes a projected target fingerprint, but still emits actions and builds the dependency graph against the unprojected target. That can produce migrations that reference objects whose creation was filtered out, and the planner does not reject the plan. I also found an extractor coverage gap for constraints on foreign tables, an apply/proof fingerprint mismatch for policy and baseline-shaped plans, non-transactional apply failure-reporting issues, and SQL-file frontend edge cases around shared-object leakage and path safety. - -Most of these are not signs that the architecture is wrong. They are places where a good abstraction is being bypassed or only partially applied. The main improvement theme is: once a view of the catalog has been resolved, make that view the only source of truth for the rest of the pipeline. - -## Validation performed - -The following local checks passed after installing dependencies: - -| Check | Result | -| --- | --- | -| `cd packages/pg-delta-next && bun run check-types` | Passed | -| `cd packages/pg-delta-next && bun test src/` | Passed, 261 tests | -| `bun run format-and-lint` | Passed | -| `cd packages/pg-delta-next && PGDELTA_NEXT_ONLY=foreign-data-wrapper-operations--full-lifecycle PGDELTA_TEST_IMAGE=postgres:17-alpine bun test tests/engine.test.ts` | Passed | - -I also ran two targeted probes: - -- a policy-filtered planner probe showing a table can be emitted with a column type provided by an extension whose `add` delta was filtered out; -- a PostgreSQL/testcontainers extraction probe showing a foreign table check constraint exists in `pg_constraint` but is not extracted as a constraint fact. - -I did not run the full corpus, the full differential/generative suite, or a long-running performance profile.

The returned `source.fingerprint` is therefore the fingerprint of the resolved planning view, not necessarily the raw extracted database. - -`apply()` then extracts the current target database and compares the raw `current.factBase.rootHash` against `thePlan.source.fingerprint`. It does not reconstruct the same policy/capability/baseline view first. This rejects valid policy-scoped plans whenever excluded objects are present in the real database. - -Baseline is more problematic: the plan does not carry enough baseline data for `apply()` or `provePlan()` to reconstruct the planning view. `provePlan()` accepts policy/capability, but not baseline. A baseline-subtracted plan can therefore be planned, but the default apply/proof gate cannot reliably validate the same source shape. - -Recommended fix: - -- Store the view metadata required to reconstruct the planning source and target in the plan artifact. -- At minimum, distinguish raw source fingerprint from resolved-view source fingerprint. -- For baseline plans, store a baseline fingerprint plus enough information to load or embed the baseline fact base. -- Make `apply()` run the same `resolveView` before checking fingerprints, or make the API explicit that `apply()` gates raw catalogs only and cannot safely apply view-shaped plans. -- Add policy and baseline apply/proof tests. The policy test should include an excluded object on the target database and confirm the fingerprint gate still accepts the plan when the scoped view matches. - -### P1: Foreign-table constraints are silently omitted from extraction - -Files: - -- `packages/pg-delta-next/src/extract/extract.ts:582` -- `packages/pg-delta-next/src/extract/extract.ts:591` -- `packages/pg-delta-next/src/extract/extract.ts:592` -- `packages/pg-delta-next/COVERAGE.md:7` - -The coverage docs say constraints and foreign tables are modeled.

Proof can pass vacuously because neither side contains the missing fact. The diagnostic system may emit a dangling dependency edge, but that is not a substitute for modeling the object. - -Recommended fix: - -- Include `relkind = 'f'` in the constraint extractor for supported constraint types. -- Confirm serializer rules emit the correct `ALTER FOREIGN TABLE` syntax when needed. If PostgreSQL accepts `ALTER TABLE` for these forms, document that choice with a regression. -- Add a corpus scenario or integration test for a foreign-table check constraint add/drop/change. -- Update `COVERAGE.md` to distinguish "modeled family, partially scoped" from "fully modeled". - -### P1: Non-transactional apply can misreport state and leak session settings - -Files: - -- `packages/pg-delta-next/src/apply/apply.ts:142` -- `packages/pg-delta-next/src/apply/apply.ts:148` -- `packages/pg-delta-next/src/apply/apply.ts:157` - -For non-transactional actions, `apply()` sets session-level parameters, executes the SQL, and then runs `RESET ALL`. If the action fails, execution jumps to the catch block before `RESET ALL`. The pooled client can be released with altered `lock_timeout`, `statement_timeout`, or `check_function_bodies`. - -There is also a reporting issue. Failed non-transactional DDL can leave durable side effects even when the SQL statement reports failure. Examples include interrupted concurrent index builds that leave invalid indexes behind. The current catch path reports all remaining actions as `unapplied`, which can falsely imply the target is unchanged. - -The reverse problem can happen if the DDL succeeds but `RESET ALL` fails: the action is reported as failed even though its side effect already occurred. - -Recommended fix: - -- Wrap reset logic in `finally`. -- Track action state separately from session-reset state. -- For non-transactional failures, report an `inDoubt` status or equivalent. The caller needs to know that the database may require re-extraction before retrying. -- Add a regression using a deliberately failing non-transactional action and assert session state is reset before client release. - -### P1: SQL-file frontend shared-object leak detection is asymmetric - -Files: - -- `packages/pg-delta-next/src/frontends/load-sql-files.ts:319` -- `packages/pg-delta-next/src/frontends/load-sql-files.ts:332` -- `packages/pg-delta-next/src/frontends/load-sql-files.ts:358` - -The loader documentation says `databaseScratch` snapshots `pg_roles` and `pg_auth_members` and throws if the sets differ after loading SQL files.

In practice, a focused extraction probe printed a very large number of `dangling_edge` diagnostics for `pg_catalog` and `information_schema` views, domains, schemas, and procedures. - -This is not just cosmetic. The diagnostic stream is the Interface by which the extractor tells a user, "I saw something important that the model did not." If hundreds of expected system edges are reported, real user-facing issues can be buried. In my foreign-table constraint probe, the missing constraint showed up only indirectly as one dangling edge among a flood of system diagnostics. - -Recommended fix: - -- Move the system-scope filter into the dependency endpoint resolver, not only into downstream diagnostics. -- Treat built-in endpoints as `null` unless the model intentionally emits the corresponding built-in fact. -- Keep user-schema dangling edges loud. -- Add a small diagnostic budget test: extracting a simple database with FDWs/views should not produce pages of system dangling edges. - -### P2: Proof auto-seeding collides on dotted identifiers - -Files: - -- `packages/pg-delta-next/src/proof/prove.ts:160` -- `packages/pg-delta-next/src/proof/prove.ts:196` -- `packages/pg-delta-next/src/proof/prove.ts:221` - -`tableStats` uses string keys like `${schema}.${name}`. `autoSeedEmptyTables` later splits the key on `"."`. - -PostgreSQL identifiers can contain dots.

If PostgreSQL reports `25001`, it retries the entire file outside the transaction. - -This is understandable as a pragmatic loader for statements such as `CREATE INDEX CONCURRENTLY`, but the Module's behavior is ambiguous when a file contains multiple statements around a non-transactional statement. The raw retry may partially apply statements before failing, and callers do not get a structured "in doubt" result. - -Recommended fix: - -- Require non-transactional statements to live in singleton files. -- Detect and fail early when a file mixes transaction-only and non-transactional statements. -- If statement splitting is needed, prefer a proven parser or server-side strategy rather than ad hoc string parsing. - -### P3: Idle pool errors are swallowed - -File: - -- `packages/pg-delta-next/src/cli/pool.ts:14` - -`makePool` attaches `pool.on("error", () => {})`. That avoids noisy unhandled errors, but it also hides connection failures that would be valuable in CLI troubleshooting. - -Recommended fix: - -- Log idle pool errors to stderr in verbose/debug mode. -- Include the connection label without printing credentials. - -## Performance and simplification opportunities - -### Use the projected fact base as the main planning Interface - -The planner already has the right Interface: `FactBase`. The policy/baseline/capability path should produce another `FactBase`, and every later step should treat that as the complete world. - -That would simplify reasoning about correctness: - -```mermaid -flowchart LR - RawSource["Raw source extract"] --> SourceView["Resolved source view"] - RawDesired["Raw desired extract"] --> DesiredView["Resolved desired view"] - SourceView --> Diff["Diff"] - DesiredView --> Diff - Diff --> Policy["Delta policy filter"] - Policy --> Project["Project desired view"] - SourceView --> Plan["Plan only against source view + projected desired view"] - Project --> Plan - Plan --> Proof["Proof/apply reconstructs same view"] -``` - -Right now the code follows this diagram for fingerprinting, but not for action emission.

Replacement paths also use repeated `source.facts().find(...)` and `desired.facts().find(...)`. - -For small schemas this is fine. For large schemas, this creates avoidable `O(rounds * edges)` and repeated array-copy/search behavior in the hottest Module. - -Recommended simplification: - -- Build `factsById`, `sourceFactsById`, and `desiredFactsById` maps once. -- Build a reverse dependency index once. -- Express forced rebuild propagation as a graph reachability walk from the initially forced ids. - -This improves performance and makes the dependency logic easier to audit. - -### Keep `FactBase` deep, but expose lower-allocation iteration helpers - -Files: - -- `packages/pg-delta-next/src/core/fact.ts` -- `packages/pg-delta-next/src/core/stable-id.ts` - -`FactBase` is one of the strongest Modules in the rewrite. It hides canonicalization, hashing, and graph consistency behind a small Interface. A few consumers currently call `facts()` and then search/copy arrays. - -Potential additions: - -- `get(id: StableId): Fact | undefined`; -- `has(id: StableId): boolean`; -- `values(): Iterable`; -- `outgoingEdges(id): readonly Edge[]` already exists and is good; -- maybe `incomingEdges(id): readonly Edge[]` if reverse walks become common. - -The goal is not to make `FactBase` wider for convenience. It is to prevent consumers from rebuilding their own indices and accidentally drifting from the canonical representation. - -### Split extractor implementation by catalog family without widening the public Interface - -File: - -- `packages/pg-delta-next/src/extract/extract.ts` - -The extractor is doing the right thing architecturally: one call extracts a consistent database snapshot and returns facts, edges, and diagnostics. That is a deep Interface. - -The Implementation is now large enough that locality is suffering. Comments at the top are stale, stage-specific helper comments are stale, and a single relkind filter missed foreign-table constraints. - -Recommended shape: - -- keep `extractDatabase()` as the public Interface; -- split internal query builders by object family, for example `relations`, `constraints`, `functions`, `policies`, `publications`, `rls`, `security-labels`, `event-triggers`; -- keep shared scope and dependency resolver helpers in one place; -- add one small per-family coverage test when the family has surprising PostgreSQL scope rules. - -This is a locality improvement, not a request to invent a new abstraction layer. - -### Keep one rule registry Interface, but split rule definitions by kind - -File: - -- `packages/pg-delta-next/src/plan/rules.ts` - -The declarative rule table is valuable. It makes the planner generic and keeps object-specific DDL isolated. The file is now large enough that finding the rule for a kind is slow, and reviewing changes risks missing nearby interactions. - -Recommended shape: - -- keep a single exported registry as the planner Interface; -- move rule definitions into family files; -- compose them in `rules.ts`; -- keep shared helpers in one place. - -This preserves the current leverage while improving code review locality. - -### Treat non-transactional actions as a separate state machine - -File: - -- `packages/pg-delta-next/src/apply/apply.ts` - -Transactional apply has a simple state model: either the transaction commits or it rolls back. Non-transactional apply does not.

The extractor now covers many more object classes and includes some extension-member provenance. - -Recommended fix: - -- Replace stage-history comments with current invariants. -- If a comment is meant to describe a known limitation, link it to `COVERAGE.md`. - -### Add a newcomer architecture map - -The docs are already substantial, but a new contributor needs a short map that answers: - -- Where do facts come from? -- How does a new catalog object get modeled? -- How does planning decide ordering? -- What proves a change safe? -- Where should product-specific policy live? - -Suggested diagram: - -```mermaid -flowchart TD - Extract["extractDatabase(pool)"] --> FactBase["FactBase: facts + dependency edges"] - SqlFiles["SQL file frontend"] --> FactBase - FactBase --> Diff["diffFacts"] - Diff --> Plan["plan: rule registry + action graph"] - Plan --> Apply["applyPlan"] - Plan --> Proof["provePlan: apply + re-extract + compare"] - Policy["policy / capability / baseline"] --> Plan - Corpus["corpus scenarios"] --> Proof -``` - -Suggested "add a new object kind" checklist: - -1. Define the stable id shape. -2. Extract the fact and dependency edges from `pg_catalog`. -3. Add the rule registry entries for add/drop/replace/alter. -4. Add a focused unit test for serialization if useful. -5. Add a corpus scenario that proves roundtrip equivalence. -6. Update coverage docs. - -### Make coverage claims evidence-shaped - -`COVERAGE.md` is very useful, but the foreign-table constraint gap shows the current categories are too coarse. A better table shape would be: - -| Family | Extracted | Planned | Proven | Known scope limits | -| --- | --- | --- | --- | --- | -| Constraints | Yes | Yes | Yes | Check constraints on foreign tables covered? Exclusion constraints? | -| Foreign tables | Yes | Yes | Yes | Local constraints and options separately listed | - -This lets docs be confident without overclaiming. - -## Suggested next work order - -1. Fix the projected-target planning bug and add dependency-completeness graph assertions. -2. Fix the apply/proof fingerprint model for policy, capability, and baseline-shaped plans. -3. Patch foreign-table constraint extraction and add corpus coverage. -4. Harden non-transactional apply reporting and session reset. -5. Fix SQL-file frontend side-effect detection and path encoding. -6. Quiet expected system dependency diagnostics while preserving user-facing warnings. -7. Update stale docs and add the newcomer architecture map. -8. Profile the planner on a large extracted schema after the correctness fixes, then add reverse-edge and fact lookup indices where the profile confirms pressure. - -## Closing assessment - -The rewrite is close to having the right long-term architecture. The strongest part is the deep fact graph Interface: it gives the system a single language for extraction, planning, proof, corpus scenarios, and product policy. The main issues are not that the Modules are too abstract; they are cases where later stages still peek at the wrong catalog view or assume a simpler world than PostgreSQL allows. - -If the project tightens those view boundaries and makes proof/apply reconstruct the same world that planning saw, the implementation will be much easier to reason about and much harder to accidentally regress. diff --git a/docs/archive/pg-delta-next-followup-review-2026-06-15.md b/docs/archive/pg-delta-next-followup-review-2026-06-15.md deleted file mode 100644 index 79d3b813e..000000000 --- a/docs/archive/pg-delta-next-followup-review-2026-06-15.md +++ /dev/null @@ -1,322 +0,0 @@ -# pg-delta-next follow-up branch review - -Date: 2026-06-15 - -Branch reviewed: `feat/pg-delta-next` - -Head reviewed: `f4e15ca29c40b1280ccaef4eb24042f2b7c81c70` - -Prior review baseline: `f23fffb761d11ce04902ee35de2500d150477edc` - -## Scope - -This is a second review pass after the 2026-06-15 branch-review findings were -implemented.

That closes the exact case -where a kept fact depends on a filtered-out fact, such as a table column using an -extension type while the extension add is filtered. - -However, action emission still passes the full `desired` fact base into create -rules. Rules that inline child facts via `alsoProduces` can therefore create a -fact whose own add delta was filtered out. - -Focused repro: - -- source contains schema `app` and table `app.t`; -- desired adds column `app.t.x integer` and default `DEFAULT 42`; -- policy filters out `{ kind: "default", verb: "add" }`; -- planner keeps only `add:column`, filters `add:default`; -- emitted action is: - -```sql -ALTER TABLE "app"."t" ADD COLUMN "x" integer DEFAULT 42 -``` - -The action also marks both `column` and `default` as produced.

Reuses the existing container infrastructure - (`packages/pg-delta/tests/container-manager.ts` — import it or copy it; - copying is fine, this package owns its destiny). -4. **Engine suite (red).** For every scenario: the proof-loop test - (`plan → provePlan → assertions from meta.ts`) written against the stub - API.

Later stages add lanes (extractor ring, - differential, soak) to this workflow — it must exist from stage 0 or no - gate is evaluable. -6. **Differential baseline capture (green).** A script (not a test) that - runs the *current* `@supabase/pg-delta` `createPlan` over every scenario - and records: the statement list, apply success/failure, and the resulting - schema (via `pg_dump --schema-only` for now — the new extractor doesn't - exist yet).

Keep a - `PORTING.md` checklist mapping every original test file → scenario - directories, so coverage is auditable (the stage gate counts this). -3. While porting, translate — don't transcribe — the assertions: - - Inline SQL snapshots: identify what the snapshot was actually guarding - (an ALTER instead of drop+create? ordering? a specific clause?) and - express that as `expect.actions` / `expect.dataLoss` / `maxActions`. - Most snapshots guard nothing beyond convergence — omit `expect` then. - - Tests asserting planner internals: usually corpus-irrelevant; note - them in `PORTING.md` as "not ported — mechanism test". -4. Tag scenarios honestly: `requires: ["supabase-image"]` for the Supabase - suite (they need the base-init baseline — port those last), - `["logical-wal"]` for subscription tests, `["isolated-cluster"]` for - role/shared-object scenarios, per-PG tags where behavior is - version-specific. -5.

Plus **global rules** (written once, first): - comment, acl, securityLabel, membership — they have no per-kind variants - by construction (§3.4). -2. **Action emission**: deltas × rules → atomic actions, each carrying - `produces` / `consumes` / `destroys` fact IDs and the safety metadata. - Multi-delta atoms (delta-set rules) for the known cases: `ALTER COLUMN - TYPE` (column `set` + dependent invalidation), view replacement chains, - procedure signature changes (identity change = remove+add of a - signature-keyed fact, but rules may recognize same-name pairs). -3. **The one graph + sort** (§3.6): edges from old-state deps (teardown: - destroyer-of-X after consumers-of-X), new-state deps (build: - producer-of-Y before consumers-of-Y), identity conflicts (remove `X` - before add `X`). Deterministic Kahn with a binary-heap ready queue; - tie-break: kind weight (mine pg_dump's section ordering and the old - `custom-constraints.ts` + pg-topo's `STATEMENT_CLASS_WEIGHT` for the - initial table) → canonical ID. **Cycle = throw with the full - edge-path diagnostic.** There is no breaker module to write (guardrail 4). -4. **Compaction** (§3.6): merge adjacent actions into idiomatic compound - DDL only when no graph edge crosses the merge. Start with the two merges - that matter for readability: column definitions into `CREATE TABLE`, and - NOT NULL/defaults into column clauses. Everything else can stay - decomposed until someone complains — compaction can improve forever - without correctness risk. -5. **Plan rendering**: every action renders one SQL statement. Mine the old - serializers (`changes/*.ts` templates, `table.alter.ts`'s ~25 variants) - for the SQL-shape knowledge — port the *strings*, not the class - structure. -6. **Loud failure on missing requirements.** The graph build fails with a - structured diagnostic (the stage-1 shared type) when an action's - `consumes`/edge target is absent from the fact set — this covers both - genuine missing dependencies and holes introduced by policy filtering - (stage 8 supplies the policy negative test; the *check* lives here). -7. **The vetted lock-class table.** Net-new (the old engine has none): - populate per-DDL-form lock levels from PostgreSQL's documentation, with - a targeted unit assertion per form. This is the "vetted" tier of the - safety report (§3.7); stage 6 consumes it, stage 6 does not build it. -8. **The benchmark fixture + timing harness.** A ≥10k-object schema fixture - and an extract/diff/plan wall-time harness, run in CI from this stage on - — stage 10's performance-parity bar reads these numbers; they must exist - long before cutover to catch regressions early. -9. **Generator growth, per PR.** Each kind-batch PR extends the stage-3 - generative engine to cover the kinds it lands. The stage-10 soak is only - meaningful if the generator emits every supported kind — coverage is - tracked as a simple kind-checklist in the generator module. - -## Recommended PR sequence (each lands corpus-greens, flips `EXPECTED_RED` entries) - -1. **Skeleton + global metadata rules** — comment/acl/label/membership - over any kind whose create/drop exists; prove on trivial scenarios. -2. **Bootstrap kinds**: schema, role, extension (+ provenance-aware - behavior), language.

The extractor still treats some unrecognized -`pg_depend` endpoints as "built-in / unmodeled" and skips them quietly: - -- `packages/pg-delta-next/src/extract/extract.ts:1797` - -`COVERAGE.md` documents deliberate non-modeled kinds, but that documentation is -not enforced against the live catalog: - -- user casts -- operators -- operator classes/families -- text-search configs/dictionaries/parsers/templates -- statistics objects -- user-defined languages -- transforms - -### Why This Blocks V1 - -The proof loop reads both source and desired through the same extractor. If the -extractor is blind to a user object, the proof loop can pass vacuously. This is -exactly the risk called out in `target-architecture.md`: extractor blind spots -need an independent defense. - -For v1, the engine does not need to model every PostgreSQL object kind. But it -must never silently miss user state. - -### Technically Optimal Shape - -Add an extraction completeness Module: - -```text -packages/pg-delta-next/src/extract/unmodeled.ts -``` - -Its Interface should be small: - -```ts -export interface UnmodeledKindDiagnostic { - code: "unmodeled_kind"; - severity: "warning"; - kind: string; - count: number; - samples: string[]; -} - -export async function detectUnmodeledKinds( - client: PoolClient, -): Promise; -``` - -The Module should run after modeled extraction, append diagnostics to -`ExtractResult.diagnostics`, and be provenance-aware: - -- exclude `pg_catalog`, `information_schema`, temp, and toast objects; -- exclude extension-owned objects through `pg_depend.deptype = 'e'`; -- report user-created objects in managed schemas; -- include count and a small deterministic sample list per kind. - -This belongs at the extraction seam, not inside `plan(source: FactBase, -desired: FactBase)`. Once only a `FactBase` reaches `plan()`, the catalog -objects that were not extracted are already lost. - -### Suggested Probe Set - -Implement bounded, per-kind probes rather than one mega-query: - -- `pg_cast`: source or target type in a user namespace, not extension-owned. -- `pg_operator`: `oprnamespace` in a user namespace, not extension-owned. -- `pg_opclass` / `pg_opfamily`: namespace in user scope, not extension-owned. -- `pg_ts_config`, `pg_ts_dict`, `pg_ts_parser`, `pg_ts_template`: namespace in - user scope, not extension-owned. -- `pg_statistic_ext`: `stxnamespace` in user scope. -- `pg_language`: user-defined/procedural languages other than built-ins - (`sql`, `plpgsql`, `c`, `internal`), not extension-owned. -- `pg_transform`: type or language in user scope, not extension-owned. - -Large objects should probably remain out of strict schema coverage unless the -product wants a separate data-state warning. They are not schema DDL in the same -sense as casts/operators/statistics. - -### Strict Mode - -Default behavior: - -- emit `warning` diagnostics; -- surface them in CLI output; -- still allow planning. - -Strict behavior: - -- fail before planning if any `unmodeled_kind` diagnostic is present. - -The cleanest Interface is either: - -```ts -extract(pool, { coverage: { unmodeled: "warn" | "error" | "ignore" } }) -``` - -or: - -```ts -assertNoBlockingDiagnostics(extractResult.diagnostics, { - unmodeled: "error", -}); -``` - -I would keep the pure `plan(FactBase, FactBase)` Interface unchanged and enforce -strict coverage at the extraction/frontends seam. - -### Tests - -Add RED tests before implementation: - -- Integration: create a user-defined cast and text-search config; `extract()` - returns `unmodeled_kind` diagnostics naming both kinds. -- Integration: extension-owned operator/opclass objects from a contrib extension - do not trigger diagnostics. -- Unit: strict diagnostic gate throws on `unmodeled_kind`. -- CLI: `plan --strict-coverage` refuses to produce a plan when unmodeled user - objects exist. -- Corpus: current corpus should remain clean, with no unmodeled diagnostics. - -## Finding 2: P0/P1 — Diagnostics Need To Be Surfaced - -### Evidence - -The CLI extracts source/desired but does not print extraction diagnostics before -planning: - -- `packages/pg-delta-next/src/cli/commands/plan.ts:100` -- `packages/pg-delta-next/src/cli/commands/plan.ts:118` - -`schema apply` similarly loads SQL files and extracts the target, but does not -surface `loadResult.diagnostics` or `targetResult.diagnostics` in the main path: - -- `packages/pg-delta-next/src/cli/commands/schema.ts:179` -- `packages/pg-delta-next/src/cli/commands/schema.ts:185` - -`snapshot`, `diff`, and `drift` also extract and should have a consistent -diagnostic story. - -### Why This Matters - -Unmodeled-kind detection only closes the correctness gap if users actually see -the warning or can opt into failing on it. - -### Recommended Module - -Add a CLI diagnostic rendering Module: - -```text -packages/pg-delta-next/src/cli/diagnostics.ts -``` - -Interface: - -```ts -export function printDiagnostics( - diagnostics: readonly Diagnostic[], - options?: { failOnError?: boolean }, -): void; - -export function hasBlockingDiagnostics( - diagnostics: readonly Diagnostic[], - options: { strictCoverage?: boolean }, -): boolean; -``` - -Use it in: - -- `plan` -- `diff` -- `snapshot` -- `drift` -- `schema apply` -- `schema export`, if extraction diagnostics apply there too -- `prove`, if re-extraction diagnostics should influence the result - -The output should include severity, code, subject if present, and message. It -should not bury diagnostics behind debug logs. - -## Finding 3: P1 — `Policy.baseline` Is Inert Unless The Caller Applies It - -### Evidence - -`supabasePolicy` declares a baseline: - -- `packages/pg-delta-next/src/policy/supabase.ts:146` -- `packages/pg-delta-next/src/policy/supabase.ts:156` - -But `plan()` says baseline subtraction happens before planning: - -- `packages/pg-delta-next/src/plan/plan.ts:107` - -The baseline directory currently contains only `.gitkeep`, and the remaining -work doc says committed Supabase baselines and resolution are still missing: - -- `packages/pg-delta-next/src/policy/baselines/.gitkeep` -- `docs/remaining-work/tier-3-service-migration-baselines.md` - -### Why This Matters - -A policy field that looks declarative but is not consumed is dangerous. Users -and future agents may assume `baseline: "supabase-baseline"` changes the managed -view when it does not. - -### Recommended Shape - -Keep core `plan(FactBase, FactBase)` pure. Baseline subtraction is a frontend / -policy Adapter concern, not rule-table logic. - -Add a small baseline resolution seam: - -```ts -export interface BaselineRegistry { - resolve(id: string, context: { pgMajor: number }): FactBase; -} - -export function applyPolicyBaseline( - source: FactBase, - desired: FactBase, - policy: Policy | undefined, - registry: BaselineRegistry, -): { source: FactBase; desired: FactBase }; -``` - -Then wire that into the CLI/product planning path before calling `plan()`. - -Alternatively, if baseline consumption is intentionally caller-side for v1, -remove `baseline` from `Policy` or mark it as metadata-only in docs and types. -Do not leave it ambiguous. - -### Tests - -- Unit: `baseline: "supabase-17"` resolves and subtracts identical facts. -- Integration: fresh Supabase baseline subtraction leaves no platform-managed - residue except documented exceptions. -- CLI: Supabase policy planning exercises the committed baseline file. - -## Finding 4: P1 — The 4b Provenance Flip Is Partial - -### Evidence - -The extractor still has `notExtensionMember` anti-joins: - -- `packages/pg-delta-next/src/extract/extract.ts:80` - -`COVERAGE.md` is honest about the partial flip: - -- flipped: schemas, tables, sequences, views/materialized views, routines, - aggregates, domains, enum/composite/range types, collations; -- still filtered: sub-entity families and rare member-root kinds. - -Relevant docs: - -- `packages/pg-delta-next/COVERAGE.md:87` -- `packages/pg-delta-next/COVERAGE.md:109` -- `docs/remaining-work/tier-4-deferrals.md:11` - -The parity test’s `FLIPPED_KINDS` matches this subset: - -- `packages/pg-delta-next/tests/extension-member-parity.test.ts:30` - -### Assessment - -This is acceptable for correctness-first v1 if the scope statement is precise. -Default behavior remains safe because extension members are projected out where -they are observed, and still filtered where they are not. - -The problem is wording. Some roadmap/status docs say "4b shipped" without the -qualifier, while other docs correctly describe the deferred families. - -### Recommendation - -Rename the status conceptually: - -- "4b common member-root provenance flip shipped" -- "4b sub-entity and rare member-root families deferred" - -Do not call 4b fully complete without that qualification. - -For future completion, use the existing parity oracle: - -1. Drop the anti-join for one family. -2. Add `ext_member_of`. -3. Emit `memberOfExtension`. -4. Add the kind to `FLIPPED_KINDS`. -5. Run parity + corpus + differential. - -## Finding 5: P1 — Evidence Gates Exist, But Final V1 Evidence Is Still Needed - -### Evidence - -The branch has a real validation harness: - -- corpus proof loop: `tests/engine.test.ts`; -- differential: `tests/differential.test.ts`; -- generative soak: `tests/generative.test.ts`; -- extension-member parity: `tests/extension-member-parity.test.ts`; -- proof coverage tests: `src/proof/prove.test.ts`; -- SQL-file loader atomicity tests: `tests/load-sql-files-atomicity.test.ts`. - -The workflow does run PG 15/17/18 unit/integration and a sharded corpus: - -- `.github/workflows/pg-delta-next.yml` - -However, the v1 docs still require: - -- full differential with `PGDELTA_NEXT_DIFFERENTIAL=all`; -- agreed generative soak quota; -- real-world shakedown; -- committed Supabase baselines; -- PG18 confirmation in some cutover docs; -- migration-guide/evidence record. - -The tier-2 cutover doc explicitly says the soak quota is still TBD: - -- `docs/remaining-work/tier-2-stage-10-cutover.md:35` - -### Recommendation - -Before declaring v1, create a short evidence artifact, for example: - -```text -docs/pg-delta-next-v1-evidence.md -``` - -It should record: - -- commit SHA; -- PG versions; -- exact commands; -- pass/fail summaries; -- differential bucket counts; -- soak seed range and quota; -- corpus scenario count; -- real-world schema description, anonymized; -- known accepted differences; -- remaining deliberate exclusions. - -Suggested command set: - -```bash -cd packages/pg-delta-next - -bun run check-types - -PGDELTA_TEST_IMAGE=postgres:15-alpine bun test tests/engine.test.ts -PGDELTA_TEST_IMAGE=postgres:17-alpine bun test tests/engine.test.ts -PGDELTA_TEST_IMAGE=postgres:18-alpine bun test tests/engine.test.ts - -PGDELTA_NEXT_DIFFERENTIAL=all \ -PGDELTA_TEST_IMAGE=postgres:17-alpine \ - bun test tests/differential.test.ts - -PGDELTA_NEXT_SOAK= \ -PGDELTA_TEST_IMAGE=postgres:17-alpine \ - bun test tests/generative.test.ts -``` - -If feasible, run differential and soak on more than PG17. If that is too slow, -record why PG17 is the representative lane. - -## Finding 6: P2 — SQL Loader Should Reject Explicit Transaction Control - -### Evidence - -The loader now wraps each file in an explicit transaction: - -- `packages/pg-delta-next/src/frontends/load-sql-files.ts:56` - -This fixes ordinary mid-file failures and has tests: - -- `packages/pg-delta-next/tests/load-sql-files-atomicity.test.ts` - -But a SQL file containing explicit `COMMIT` can still commit partial DDL before -a later statement fails. The hardening plan itself identified explicit -`BEGIN`/`COMMIT` as the real narrow gap. - -### Assessment - -This is not as important as unmodeled-kind detection, but the current comment -"each file applies inside an explicit transaction" is only true for files that -do not contain transaction-control statements. - -### Recommendation - -Reject transaction-control statements in declarative SQL files with a clear -`ShadowLoadError` diagnostic. - -This can be a conservative scanner that strips comments and string literals and -then rejects statement-boundary forms: - -- `BEGIN` -- `COMMIT` -- `ROLLBACK` -- `SAVEPOINT` -- `RELEASE SAVEPOINT` -- `PREPARE TRANSACTION` -- `COMMIT PREPARED` -- `ROLLBACK PREPARED` - -This is not dependency inference and does not violate the "Postgres is the -elaborator" principle. It is a loader safety check. - -## Finding 7: P2 — Comment And Roadmap Drift - -### Examples - -`pg-delta-next-hardening-plan.md` says 4b is not started in one section, then -says it shipped later: - -- `docs/pg-delta-next-hardening-plan.md:219` -- `docs/pg-delta-next-hardening-plan.md:434` - -`IdFieldPredicate` still says typos silently never match, but validation now -rejects unknown fields: - -- `packages/pg-delta-next/src/policy/policy.ts:127` -- `packages/pg-delta-next/src/policy/policy.ts:650` - -`plan.ts` still has the old first-consumer `commitBoundaryAfter` boundary logic: - -- `packages/pg-delta-next/src/plan/plan.ts:658` - -`apply.ts` now correctly treats `commitBoundaryAfter` as an unconditional -segment boundary: - -- `packages/pg-delta-next/src/apply/apply.ts:46` - -### Recommendation - -Clean these before v1. They are not major correctness risks, but they increase -the chance that the next model or maintainer implements against the wrong mental -model. - -## Non-Blockers For Correctness-First V1 - -### Extension-Intent Phase B - -Phase B is absent in code, as the docs say: - -- no `extensionIntent` kind; -- no `intentRules`; -- no pgmq / pg_cron handlers; -- no replay actions. - -This should not block correctness-first v1 unless the product promises -from-empty rebuild fidelity for pgmq queues, cron jobs, or partman parents. -Current docs sensibly move this to post-v1 / DX. - -### Performance - -Serial extraction is correct because it runs under one repeatable-read read-only -transaction. Parallel snapshot workers are a performance optimization, not a -correctness requirement. - -### Planner Refactor - -The planner is still large, but the current split is reasonable: - -- `plan.ts` keeps the cohesive mutation-heavy algorithm; -- `internal.ts` owns graph construction, tie keys, compaction, and safety report; -- `rules.ts` remains the per-kind rule table. - -Further splitting is optional polish. It should not precede the v1 correctness -items above. - -## Suggested Pre-V1 Work Plan - -### Step 1: Implement Unmodeled-Kind Detection - -Files likely touched: - -- `packages/pg-delta-next/src/extract/unmodeled.ts` -- `packages/pg-delta-next/src/extract/extract.ts` -- `packages/pg-delta-next/src/core/diagnostic.ts` if the diagnostic type needs - a typed code union -- integration tests under `packages/pg-delta-next/tests/` - -Done when: - -- user-created unmodeled catalog objects produce diagnostics; -- extension-owned variants do not produce noise; -- strict mode can fail on diagnostics; -- corpus remains clean. - -### Step 2: Surface Diagnostics In CLI/Frontend Paths - -Files likely touched: - -- `packages/pg-delta-next/src/cli/diagnostics.ts` -- `packages/pg-delta-next/src/cli/commands/plan.ts` -- `packages/pg-delta-next/src/cli/commands/diff.ts` -- `packages/pg-delta-next/src/cli/commands/snapshot.ts` -- `packages/pg-delta-next/src/cli/commands/drift.ts` -- `packages/pg-delta-next/src/cli/commands/schema.ts` -- possibly `packages/pg-delta-next/src/cli/commands/prove.ts` - -Done when: - -- warnings print by default; -- `--strict-coverage` or equivalent fails before producing a plan; -- tests prove both behaviors. - -### Step 3: Resolve Or Remove `Policy.baseline` - -Files likely touched if wiring: - -- `packages/pg-delta-next/src/policy/baseline.ts` -- `packages/pg-delta-next/src/policy/supabase.ts` -- `packages/pg-delta-next/src/policy/baselines/*.json` -- CLI planning path -- tests for baseline resolution - -Done when one of these is true: - -- `Policy.baseline` actually resolves and subtracts a committed baseline; or -- the field is removed/renamed so nobody thinks it is active. - -### Step 4: Clean V1 Status Docs - -Files likely touched: - -- `docs/pg-delta-next-remaining-work.md` -- `docs/pg-delta-next-hardening-plan.md` -- `docs/remaining-work/README.md` -- `docs/remaining-work/tier-4-deferrals.md` -- `packages/pg-delta-next/README.md` -- `packages/pg-delta-next/COVERAGE.md` - -Done when: - -- the 4b status is consistently described as partial/common-root shipped; -- unmodeled-kind detection is either marked done or remains the only blocker; -- strict coverage behavior is documented; -- unsupported kinds are documented as "diagnosed, not silently ignored." - -### Step 5: Run And Record The V1 Evidence Gates - -Create or update: - -- `docs/pg-delta-next-v1-evidence.md` - -Done when: - -- corpus is green on supported PG versions; -- `EXPECTED_RED` is empty or deleted according to the cutover plan; -- full differential is run and bucket counts are recorded; -- soak quota is agreed and recorded; -- real-world shakedown is recorded; -- Supabase baseline path is exercised or explicitly excluded from v1. - -## Final Call - -The implementation is technically strong and mostly aligned with the documents. -The managed-view architecture is the right abstraction: it gives callers -leverage through one view Interface and gives maintainers locality for scope, -provenance, capability, and proof honesty. - -The remaining correctness work is concentrated and tractable.

Read the rest of pg_subscription (version-gating run_as_owner/origin to PG16+ and normalising substream's PG15-bool / PG16-char shape to the streaming keyword); carry them on the payload; render every captured option in CREATE SUBSCRIPTION's WITH (a fresh subscription has no prior fact, so the per-attribute ALTER rules never fire for it); and add in-place ALTER SUBSCRIPTION … SET (opt = …) rules for the settable options. two_phase recreates instead — PostgreSQL forbids toggling it on an enabled subscription. Covered by a focused unit test (src/plan/subscription-options.test.ts) and the subscription-operations--replication-options corpus scenario; the existing subscription-operations--alter-configuration scenario now exercises binary/synchronous_commit/disable_on_error end-to-end too.

Because +the renderer's `qid()` **always** double-quotes, every engine-rendered +`ALTER TABLE "s"."t" …` hit this when formatting was enabled: + +``` +ALTER TABLE "public"."users" ADD + COLUMN a int +``` + +This affected **all** `ALTER TABLE` forms (`ADD COLUMN`, `ENABLE ROW LEVEL +SECURITY`, `REPLICA IDENTITY`, …) and the sibling `formatAlterGeneric` +(`ALTER MATERIALIZED VIEW`/`DOMAIN`/`FOREIGN TABLE`/…). + +**Fixed:** both `formatAlterTable` and `formatAlterGeneric` now find the name's +true end from the raw statement via `qualifiedNameEnd` (the helper the +CREATE-family formatters already use), instead of positional token indexing. +Regression coverage lives in `format-quoted-names.test.ts`. + +**Remaining follow-up (same root cause, different symptom):** +`keyword-case.ts` (`isCaseableInContext` / the ALTER handler around line 846) +still uses `skipQualifiedName` to find the action-token region, so for a +quoted-name `ALTER TABLE` the per-action keyword-casing loop starts one token +late and can skip casing the first action keyword. Lower severity (casing, not +stranding) — fix it the same way (anchor on `qualifiedNameEnd`) when the +keyword-case pass is next touched. + +## P2 — contract & coverage gaps + +### pg-delta CI does not re-run on pg-topo changes — ✅ resolved in this PR + +`.github/workflows/tests.yml` gated the pg-delta unit/integration/check-types +jobs on `packages/pg-delta/**` (or root) only. A pg-topo-only change — like this +PR's `ordered` contract change — never re-ran pg-delta's suites, even though +pg-delta imports `@supabase/pg-topo` at runtime. (The merge queue forces all +outputs true, so the gap was real at PR-review time but masked at merge time.) + +**Fixed:** the `pg-delta` check-types step, `pg-delta-unit`, +`pg-delta-test-image-hash`, and `pg-delta-integration` jobs now also fire on +`needs.detect-changes.outputs.pg-topo == 'true'`. The `detect-changes` action +already emitted a `pg-topo` output, so no filter change was needed. `knip +(pg-delta)` was intentionally left on the pg-delta-only gate — it inspects +pg-delta's own unused code, which a pg-topo change cannot affect. + +### Changesets version a private package — ✅ resolved in this PR + +55 changesets target `@supabase/pg-delta-next`, which is `"private": true` / +`0.0.0`. The repo is in changeset pre-release (alpha) mode and +`.changeset/pre.json`'s `initialVersions` doesn't list pg-delta-next, so +`changeset status` planned a **minor** bump for it — the release workflow would +have consumed all 55 into a `chore: release` PR that bumps the unpublishable +package and writes a large CHANGELOG (`changeset publish` skips private packages, +so this was churn, not breakage). + +**Fixed:** added `@supabase/pg-delta-next` to `.changeset/config.json` `ignore`. +This is safe and non-destructive — all 55 changesets are standalone (they +reference no other package) and no published package depends on pg-delta-next, so +`ignore` neither errors nor cascades. The changesets are preserved (ignored +changesets aren't consumed) and `changeset status` now plans only +`@supabase/pg-topo` (patch). When pg-delta-next is eventually published, remove +it from `ignore` to release the accumulated history. + +### `elideCascadeSubsumedPolicyDrops` ignores policy→role references + +`packages/pg-delta-next/src/plan/internal.ts` judges whether a dropped object is +load-bearing from `pg_depend` edges only. A policy's referenced roles live in +`pg_shdepend` and are carried on the fact payload (`roles`), not as graph edges, +so a role-referencing policy's `DROP POLICY` can be elided as cascade-subsumed. +The `DROP OWNED BY ; DROP ROLE ` sequence in `rules/roles.ts` covers +the general case, but the sole-role-in-policy ordering is untested +(`policy-drop-compaction.test.ts` covers only the view case). **Follow-up:** add +the role scenario to the corpus. + +### `elideCoCreateRevokeBeforeGrant` guard reads only desired facts + +The `defaultGrantsOutside` guard in `internal.ts` inspects only **desired** +`defaultPrivilege` facts, so a *source-only* `ALTER DEFAULT PRIVILEGES` being +dropped in the same plan can still fire at create time — leaving the applied ACL +a superset of desired. The proof loop diffs ACLs post-apply, so any +corpus-covered scenario is safe; an uncovered one ships undetected. +**Follow-up:** add a corpus scenario that drops a source-only ADP alongside a +co-created grant. + +### pgmq tables excluded by a name-glob bandaid + +`packages/pg-delta-next/src/policy/supabase.ts` re-includes user triggers in +managed schemas, then carves pgmq's `q_*`/`a_*` queue/archive tables back out by +name glob (scoped to the `pgmq` schema). The comment concedes this compensates +for pgmq creating its tables via `pgmq.create()` rather than `CREATE EXTENSION`, +so extract-time `pg_depend` `'e'` membership misses them. If pgmq changes its +internal naming — or a user creates a `q_*` table inside the pgmq schema — the +classification is wrong. **Deeper fix:** tag pgmq-created objects as +extension/owner-owned at extraction time so the generic ownership exclusion +covers them. + +### `$1$…$1$` digit dollar-tags mis-scanned + +`sql-scanner.ts`'s `readDollarTag` (and the regex in `load-sql-files.ts`) accept +digit-leading dollar tags, so `$1$…$1$` is treated as a dollar-quoted span even +though Postgres parses `$1` as a positional parameter. Unlikely in +engine-rendered SQL; low severity but a real divergence from Postgres +tokenization. + +## P3 — cleanup (batch into a follow-up chore PR) + +- **Three hand-rolled SQL scanners, two disagreeing.** `walkSql` + (`sql-scanner.ts`) and `protectDollarQuotes` (`protect.ts`) don't nest-count + block comments; `maskLiteralsAndComments` (`load-sql-files.ts`) does.

Split + into `parseApplyFlags` / `resolveScopeAndProfile` / `prepareFiles` / + `resolveShadow` / `runApply`, add a `parseEnumFlag` helper. +- **Perf nits:** `internal.ts` teardown scans the full edge list per destroyed + id (use the existing `incomingEdgesByEncoded` reverse index, cf. + `replacement-expansion.ts`); `diff.ts` and `snapshot.ts` sort comparators + rebuild keys per comparison (Schwartzian transform); `keyword-case.ts` makes + two full passes (scanTokens + walkSql); `load-sql-files` does 3 round-trips per + file; `schema.ts` calls `mkdirSync` per exported file. +- **Test/script infra duplicated from pg-delta:** `tests/containers.ts` and + `scripts/sync-supabase-base-images.ts` re-derive helpers that already exist in + pg-delta's test/script harness (`ensureSupabaseDbMajorVersion` is already + exported). `collectSqlFiles` duplicates pg-topo's `discoverSqlFiles`. `hash.ts` + vs pg-delta `fingerprint.ts` is likely a deliberate independent equality + surface — add a comment saying so, so nobody "fixes" it by importing. +- **`protect.ts` body-protection kind list** is hand-maintained and disconnected + from the per-kind rule metadata the renderer uses; drive it from the same + metadata so the formatter and plan agree on which kinds carry an opaque body. +- **`formatters.ts` repetition:** ~18 hand-written command-prefix guards and a + copy-pasted parenthesized-list assembly → `matchesPrefix` + `formatParenBlock` + helpers. +- **`pg-delta-next.yml` uses bare `bun test`.** The repo convention is + `bun run test`; here the package `test` script carries no extra flags so it is + harmless, but align it or note the exception explicitly. + +## Documented, by-design (no action — recorded so they aren't re-flagged) + +- **`rootHash` folds reference-only facts** (`core/fact.ts`). Intentional: the + apply fingerprint gate relies on it, so a plan is only applicable against the + same baseline.

Consumers that care must filter + `referenceOnly`; the load-bearing ones already do. +- **pg-topo README** states `ordered` "always contains every input statement + exactly once." Accurate for *statements*, but a file that fails parsing + contributes zero statement nodes and is therefore absent. pg-delta's + declarative-apply has no `PARSE_ERROR` fallback, so a parse failure yields a + silently-incomplete apply reported as success. Doc-wording + consumer-hardening + follow-up. +- **Deleted dogfood differential harness** (`differential.test.ts`, + `old-engine.ts`).

The old engine remains available in git history and on npm as 1.0.0-alpha.31. - Move packages/pg-delta-next -> packages/pg-delta; delete old engine. - Rename package to @supabase/pg-delta (un-private), keep the `pgdelta` binary, restore publish metadata (files/main/types/repository/...). - Add a Node-consumable build: tsc with rewriteRelativeImportExtensions emits dist/*.js + *.d.ts from the .ts-extension source; dual bun/import/require/types/default conditional exports (bun serves TS source directly, Node serves compiled dist). CLI shebang -> node. - Drop @supabase/pg-delta-next from the changesets ignore list. - Update public-api.test for the dual-export shape; add knip.json (export/type hygiene downgraded to warn pending follow-up cleanup). BREAKING CHANGE: @supabase/pg-delta is now the clean-room engine with a new CLI/API surface; nothing carries over from the legacy engine.

` event/table clause, producing invalid migration SQL. The tokenizer skipped double-quoted identifiers entirely, so the trigger formatter mistook the next keyword for the trigger name and sliced away everything before the first recognized clause. The tokenizer now emits an atomic token for double-quoted identifiers, which also fixes the same latent issue for other object types whose names follow a keyword positionally (subscriptions, servers, foreign data wrappers, etc.). - -- Updated dependencies [c06f081] - - @supabase/pg-topo@1.0.0-alpha.3 - -## 1.0.0-alpha.30 - -### Major Changes - -- c4b90f5: Replace the flat `plan.statements` list with execution-aware migration units. - - A plan is now an ordered list of `MigrationUnit`s (`plan.units`) plus session-level statements (`plan.sessionStatements`). Each unit carries an explicit `transactionMode` and a boundary `reason`, so plans whose statements cannot share one transaction are represented and applied correctly: - - - `ALTER TYPE ... ADD VALUE` and any later statement now run in separate transactions, fixing PostgreSQL error 55P04 ("unsafe use of new value of enum type") when a migration adds an enum value and uses it (#262). - - Statements PostgreSQL rejects inside a transaction block — `ALTER SUBSCRIPTION ... SET PUBLICATION` with implicit `refresh = true`, `DROP SUBSCRIPTION` with an associated replication slot — are applied as standalone non-transactional units instead of failing inside `BEGIN`/`COMMIT`. - - `CREATE SUBSCRIPTION` for a subscription whose replication slot already exists now emits `create_slot = false` (keeping `connect = true`), so the existing slot is reused instead of failing with "replication slot already exists"; that form is transactional (PostgreSQL's transaction-block gate is on `create_slot = true`). - - Execution semantics are declared on the change classes (`nonTransactional`, `commitBoundary`), never inferred from rendered SQL. - - **Migrating from `plan.statements`:** - - ```ts - // before - const script = plan.statements.join(";\n"); - - // after — transaction-aware script (BEGIN/COMMIT per unit, unit headers) - const script = renderPlanSql(plan); - // or one numbered file per unit (also: pgdelta plan --output-dir ) - const files = renderPlanFiles(plan); - // or the raw ordered statements (session statements included) when - // transaction context does not matter - const statements = flattenPlanStatements(plan); - ``` - - **`applyPlan` result changes:** - - ```ts - // before - | { status: "applied"; statements: number; warnings?: string[] } - | { status: "failed"; error: unknown; script: string } - - // after - | { status: "applied"; statements: number; units: number; warnings?: string[] } - | { status: "failed"; error: unknown; script: string; - failedUnitIndex?: number; completedUnits: number } - ``` - - **Behavioral consequences:** - - - Multi-unit plans are **not atomic as a whole**: earlier units commit before later units run, and a later failure does not roll back already-committed units (an added enum value cannot be dropped). `applyPlan` reports the failing unit and how many units committed. - - Non-transactional units run without any transaction wrapper. Rendered scripts must be executed by a statement-splitting runner such as `psql -f` (not as a single multi-statement query string, and not with `psql --single-transaction`): PostgreSQL runs multi-command strings in an implicit transaction block, which would fail any non-transactional unit. - - Single-unit plans (the common case) still apply as one transaction. - - **Plan JSON:** new plans are written as `version: 2` with `units`. Legacy v1 plan files (flat `statements`) are still read and normalized into a single transactional unit — faithful to how v1 executed them — but v2 plan files are not readable by older pg-delta versions. - - **New:** unorderable dependency cycles now throw a typed `UnorderableCycleError` (exported) carrying the offending changes in `error.cycle`, instead of a plain `Error` that callers had to string-match. And `pgdelta plan --output-dir ` writes one numbered, transaction-aware SQL file per migration unit. - -## 1.0.0-alpha.29 - -### Patch Changes - -- 115dde8: Fix unhandled `CycleError` when dropping a FK chain of tables alongside a referenced unique constraint while only some of the involved tables are publication members.

The trigger extractor already drops these via the `pg_depend deptype='e'` row that pgmq records, but real-world cloud projects can lose that row (older pgmq versions — pgmq `1.4.4` which Supabase Cloud currently ships never records it — manual `pg_dump`/restore that strips extension deps, etc.), so `supabase db reset` aborts at the trigger statement with `relation "pgmq.q_" does not exist`. Add a defensive name-match fallback in the supabase integration filter so the trigger is dropped even when the principled signal is missing. - -- 71cce8a: fix(pg-delta): suppress Wasm FDW servers, foreign tables, and user mappings in supabase integration - - Follow-up to CLI-1470. Also suppress SERVER (object/comment/security-label scopes), FOREIGN TABLE, and USER MAPPING changes whose parent wrapper is a Supabase Wasm FDW — identified by the `extensions.wasm_fdw_handler` / `extensions.wasm_fdw_validator` functions the `wrappers` extension ships — so `db pull` no longer emits `CREATE SERVER clerk_oauth_server` for platform Wasm FDWs that local Docker cannot provision. - - The discriminator is the Wasm handler/validator function names, not the bare `extensions.*` namespace: contrib FDWs like `postgres_fdw` install their handler/validator into `extensions` on Supabase too, but they ARE available in the local image, so user-created `postgres_fdw` wrappers (and their servers, foreign tables, and user mappings) must still roundtrip. Server _privilege_ scope is likewise preserved — `GRANT/REVOKE ON SERVER` does not require superuser. - -## 1.0.0-alpha.26 - -### Patch Changes - -- 82d4700: feat(pg-delta): emit `VALIDATE CONSTRAINT` shortcut when only `validated` flips from false to true - - When the only difference between main and branch for an existing table constraint is `convalidated` flipping from `false` to `true` (i.e. the user wants to validate a previously `NOT VALID` constraint), pg-delta now emits a single `ALTER TABLE ... VALIDATE CONSTRAINT ...` instead of dropping and re-adding the constraint. - - `VALIDATE CONSTRAINT` only takes `SHARE UPDATE EXCLUSIVE` on the table (concurrent reads and writes continue while the row scan runs), whereas drop+add takes `ACCESS EXCLUSIVE` for the duration of the scan. This matches the standard "ADD CONSTRAINT ... NOT VALID; later VALIDATE CONSTRAINT" two-phase safe-migration pattern. - - The reverse direction (`validated` → `NOT VALID`) has no equivalent Postgres command, so it still goes through drop+add. Any other field change (expression, key columns, FK target, on_delete, etc.) on top of a `validated` flip also still goes through drop+add — the shortcut applies only when nothing else differs. - -- 6d49e04: fix(pg-delta): clear the connect-timeout timer when the race settles - - `createManagedPool` raced `pool.connect()` against a `setTimeout` rejection but never cleared the timer. When the connect won (the normal, fast case), the pending `setTimeout` kept the event loop alive, so the process hung for the rest of `PGDELTA_CONNECT_TIMEOUT_MS` even though the plan was already done. Raising the timeout for far-away databases made every local run wait that long too. The race now goes through a `connectWithTimeout` helper that clears the timer in a `.finally`. - -- 82d4700: fix(pg-delta): stop re-validating NOT VALID constraints - - A NOT VALID constraint was followed by a VALIDATE CONSTRAINT step that flipped it back to validated, so the plan never converged. ADD CONSTRAINT already carries the NOT VALID suffix, so the VALIDATE was redundant. It's now dropped from the create, alter, and table-replacement paths. - -## 1.0.0-alpha.25 - -### Patch Changes - -- f1704bd: fix(pg-delta): keep user-defined triggers on auth/storage tables through the supabase filter - - User-attached triggers on `auth.users`, `storage.objects`, etc. were being dropped from `supabase` integration diffs because triggers live in their parent table's schema and inherit its owner — both signals the Supabase managed-schema filter uses to skip Supabase's own objects. The filter now keeps any trigger whose function lives outside the managed schemas, which is the reliable user-defined marker. - -- 62f39d4: fix(pg-delta): emit valid GRANT/REVOKE syntax for ordered-set, hypothetical-set, and variadic aggregates - - `GrantAggregatePrivileges` / `RevokeAggregatePrivileges` / - `RevokeGrantOptionAggregatePrivileges` previously serialized the - aggregate signature using `pg_get_function_identity_arguments`, which - embeds `ORDER BY` for ordered-set / hypothetical-set aggregates - (`aggkind` of `o` / `h`) and `VARIADIC` for variadic aggregates. The - PostgreSQL `GRANT ... ON FUNCTION` parser rejects both keywords inside - the argument list, so the generated `GRANT`/`REVOKE` failed with a - syntax error for any aggregate that wasn't a plain `aggkind = 'n'`. - The serializer now uses the `proargtypes`-derived `argument_types` - list, matching the signature shape PostgreSQL expects for `GRANT`/`REVOKE`. - -- ae4c499: fix(pg-delta): skip redundant `ALTER TABLE … ADD CONSTRAINT` for CHECK constraints inherited by partition children - - Previously the inheritance signal used `pg_constraint.conparentid <> 0`, but PostgreSQL only populates `conparentid` for PK / UNIQUE / FK constraints on partitions — CHECK constraints on partitions always have `conparentid = 0`. As a result, pg-delta re-emitted every inherited CHECK constraint against each partition, and apply failed with SQLSTATE 42710 ("constraint already exists") because the constraint had already been auto-created on the partition by Postgres when the parent's constraint or the partition itself was created. The extractor now uses `coninhcount > 0`, the canonical inheritance flag, which covers CHECK and all other constraint kinds uniformly. - -- 0d52b68: Redact foreign-data-wrapper option values that are not on the allowlist of known-safe keys (libpq connection params, postgres*fdw behavior knobs, generic table-FDW shape, Supabase Wrappers non-credential keys). The policy applies to `CREATE / ALTER FOREIGN DATA WRAPPER`, `CREATE / ALTER SERVER`, `CREATE / ALTER USER MAPPING`, and `CREATE / ALTER FOREIGN TABLE` — every value is replaced with `\_\_OPTION*\_\_`unless the key is recognised as safe. Previously credentials such as`password`, `passfile`, `passcode`, `sslpassword`, `api_key`, `private_key`, `aws_secret_access_key`, etc. were emitted in cleartext into plan SQL, catalog snapshots, declarative export, and fingerprints, ending up on disk and in CI logs (CLI-1467). Safe-listed options (`host`, `port`, `user`, `dbname`, `sslmode`, `fetch_size`, `region`, `endpoint`, …) continue to roundtrip with their real values. The emitted DDL is not directly re-appliable for redacted options — operators must re-supply credentials out of band. -- 62f39d4: fix(pg-delta): suppress GRANT/REVOKE on FOREIGN DATA WRAPPER in the supabase integration - - `GRANT`/`REVOKE ... ON FOREIGN DATA WRAPPER` requires superuser. On Supabase Cloud the `postgres` role has the elevated rights to apply these grants, but the local Docker image does not — so the previous diff output broke `supabase db reset` with `permission denied for foreign-data wrapper dblink_fdw`. The existing system-role rule already covers wrappers owned by `supabase_admin`, but `pg_dump` rewrites OWNER TO clauses to whoever the dump runs under, so after a restore the FDW ends up owned by `postgres` and slips past the owner gate. The supabase integration filter now drops privilege-scope changes on `foreign_data_wrapper` regardless of owner, since the FDW ACL is never user-replayable in the local image. `FOREIGN SERVER` ACL is intentionally left alone — server GRANT/REVOKE doesn't require superuser, and user-created servers (e.g. a `dblink` server pointing to a peer DB) carry legitimate user ACL that should still roundtrip. - -- 62f39d4: fix(pg-delta): suppress CREATE/DROP/ALTER FOREIGN DATA WRAPPER for platform-managed Wasm wrappers in the supabase integration - - The `supabase` integration now skips any FDW whose `HANDLER` or `VALIDATOR` references a function in the `extensions` schema. This covers the Wasm-based wrappers (`clerk`, `clerk_oauth`, etc.) that Supabase Cloud provisions as `supabase_admin` at project creation. `CREATE FOREIGN DATA WRAPPER` requires superuser, and the local Docker image has no equivalent pre-step, so the previous diff output broke `supabase db reset`. Owner-based filtering wasn't enough because the wrapper owner is often rewritten away from `supabase_admin` after a dump/restore. - -## 1.0.0-alpha.24 - -### Patch Changes - -- 471f770: Fix drop-phase cycle breaking when publication table membership removal intersects with dropped foreign-key chains and a referenced constraint drop. -- 471f770: Fix `DropSequence ↔ DropTable` drop-phase cycle when an owning table is - promoted to `DropTable + CreateTable` by `expandReplaceDependencies` (for - example when a referenced enum has a label removed) and the same plan also - drops the SERIAL sequence because branch no longer carries the owned sequence. - - `diffSequences.dropped` short-circuits `DropSequence` only when the owning - table itself is absent from the branch catalog. When the table survives in - branch but is later replaced via expansion (table is in `replacedTableIds`), - the explicit `DROP SEQUENCE` survives into the drop phase alongside the - expander's `DropTable`, and the bidirectional pg_depend edges between the - sequence and its owning column close an unbreakable 2-cycle that none of the - existing dependency-filter / change-injection breakers match. - - `normalizePostDiffChanges` now prunes `DropSequence(S)` whenever S is `OWNED -BY` a column on a table in `replacedTableIds`. The `DROP TABLE` cascade - already drops the OWNED BY sequence at apply time, so the explicit - `DROP SEQUENCE` was both redundant and the source of the cycle. - -## 1.0.0-alpha.23 - -### Minor Changes - -- 9a0831a: feat(pg-delta): add support for PostgreSQL SECURITY LABEL across all 17 supported object types (schemas, tables, columns, views, materialized views, sequences, functions, procedures, aggregates, composite/enum/range types, domains, event triggers, foreign tables, publications, subscriptions, roles). Includes round-trip fidelity, a new `scope: "security_label"` in the filter DSL, and per-provider filtering via the new `provider` extractor. - -### Patch Changes - -- 9a0831a: Expose security-label providers to the filter DSL so provider-specific security label filters work as documented. - -## 1.0.0-alpha.22 - -### Minor Changes - -- 2d1991a: feat(pg-delta): retry catalog extractors when `pg_get_*def()` returns NULL - - `pg_get_indexdef`, `pg_get_constraintdef`, `pg_get_viewdef`, `pg_get_triggerdef`, `pg_get_ruledef`, and `pg_get_functiondef` can transiently return NULL when the underlying catalog row is dropped concurrently or the catalog state is in flux. Previously such rows were dropped silently after one attempt; now extraction retries the affected query a configurable number of times before falling back to filtering. In practice the second attempt no longer sees the dropped object (or successfully resolves the definition), so a real CREATE/DROP racing with `createPlan` is reliably preserved or excluded rather than half-captured. - - Configuration (precedence: option > env > default): - - - `CreatePlanOptions.extractRetries?: number` — public API option on `createPlan`. - - `PGDELTA_EXTRACT_RETRIES` env var — same value, useful for CLI usage. - - Default `1` (i.e. the first attempt plus one retry, 2 attempts total). - - After retries are exhausted, rows whose `pg_get_*def()` is still NULL are filtered out and a warning is emitted via `debug('pg-delta:extract')` (visible with `DEBUG=pg-delta:extract` or `DEBUG=pg-delta:*`). Setting `extractRetries: 0` disables retrying entirely and reproduces the previous "filter-on-first-attempt" behavior. - -### Patch Changes - -- 9e3541d: fix(pg-delta): order dependency-breaking ALTERs before DROP for types, sequences, and policies (#230) - - `ALTER COLUMN ... DROP DEFAULT`, `ALTER COLUMN ... DROP IDENTITY`, and - `ALTER COLUMN ... TYPE ` are now scheduled in the drop phase so - that the catalog edges in `pg_depend` order them ahead of the matching - `DROP TYPE` / `DROP SEQUENCE`. `ALTER COLUMN ... TYPE` also drops any - existing default before the rewrite (and re-emits a `SET DEFAULT` after) - so the stale default expression cannot pin the old type. RLS policies - whose `USING` / `WITH CHECK` expressions begin or stop referencing - different functions or relations are now emitted as drop+create, letting - the policy's drop run before the referenced object's drop and the - policy's recreate run after the new object's create. Plans that - previously aborted with PostgreSQL `2BP01` ("cannot drop ... because - other objects depend on it") now apply cleanly. - -- 2d1991a: fix(pg-delta): skip rows when `pg_get_viewdef`, `pg_get_triggerdef`, `pg_get_ruledef`, or `pg_get_functiondef` returns NULL instead of crashing the relevant `extract*` with a ZodError. Same race conditions as the prior `pg_get_indexdef` (#223) and `pg_get_constraintdef` fixes — the underlying catalog row can vanish (concurrent DDL, transient catalog state, recovery edges). A single unreadable view, materialized view, trigger, rule, or function no longer aborts the whole catalog extraction and `createPlan` call. -- 7c7d18a: fix(pg-delta): produce applyable migrations for `RENAME` operations seen as drop+create - - `pg-delta` is a state-based diff and treats a `RENAME` as `DROP+CREATE` because - the final catalogs are indistinguishable. Two scenarios in that drop+create - path failed at apply time on schemas that had been renamed in the target - (reported in [#228](https://github.com/supabase/pg-toolbelt/issues/228)): - - - A table with a `SERIAL` column renamed in the target left the same-name - sequence (e.g. `old_table_id_seq`) "altered" in the diff (only its - `OWNED BY` ref changed). `DROP TABLE` cascade-drops the sequence via - `OWNED BY`, after which the freshly created table's column default - `nextval('old_table_id_seq'::regclass)` referenced a non-existent relation - and the migration aborted. `diffSequences` now detects when the sequence's - main-side owning table is going away in the same plan and recreates the - sequence after the cascade, while suppressing an explicit `DROP SEQUENCE` - that would form an unbreakable cycle with `DropTable`. - - A table renamed in the target with a dependent view (e.g. - `CREATE VIEW user_count AS SELECT count(*) FROM users` with the table - renamed to `members`) failed with `cannot drop table users because other -objects depend on it`. `expandReplaceDependencies` now seeds drop-only - schema objects (table, view, materialized view, type, domain) as expansion - roots so any surviving dependent in `pg_depend` gets promoted to - `DROP+CREATE`. The dependent's drop is sequenced before the parent drop, - and its create runs after the new replacement is in place. - -- 3b9eb91: fix(pg-delta): preserve `REPLICA IDENTITY USING INDEX` on tables instead of silently reverting to `DEFAULT` on declarative sync. - - The table extractor only stored `replica_identity` as a single character (`'d' | 'n' | 'f' | 'i'`) and discarded the index name when the mode was `'i'`. The diff path then explicitly skipped mode `'i'` ("handled by index changes" — but no such handler existed), and `AlterTableSetReplicaIdentity.serialize()` fell back to `REPLICA IDENTITY DEFAULT` for that mode. Compounding this, `Index.is_replica_identity` participated in equality and was marked non-alterable, so toggling the flag on the index triggered a spurious `DROP INDEX` + `CREATE INDEX` — and Postgres reverts the table to `REPLICA IDENTITY DEFAULT` whenever the configured replica-identity index is dropped. - - End result: a table configured with `ALTER TABLE foo REPLICA IDENTITY USING INDEX foo_idx` would extract as `replica_identity = 'i'` but produce no setter on diff. The next `declarative sync` would generate a migration that dropped the user's index, reset the table to `DEFAULT`, and recreated the index — never converging (reported as supabase/cli#5141). - - The fix: - - - `Table.replica_identity_index` is extracted via `pg_index.indisreplident` and included in `dataFields`, so the index name participates in equality. - - `AlterTableSetReplicaIdentity` now serializes `REPLICA IDENTITY USING INDEX ` for mode `'i'` and declares the index as a `requires` dependency so it is created first. - - The table diff emits the change for all modes (including `'i'`) on both `CREATE` and `ALTER`, and re-emits when the configured index name changes while staying in `'i'` mode. - - `Index.is_replica_identity` is no longer in `dataFields` / `NON_ALTERABLE_FIELDS`; the table side is the source of truth, set via `ALTER TABLE`. This stops the spurious `DROP INDEX` + `CREATE INDEX` cycle. - - A new `restoreReplicaIdentityAfterIndexReplace` pass in `post-diff-normalization.ts` re-emits `ALTER TABLE ... REPLICA IDENTITY USING INDEX ` after any `DropIndex(idx) + CreateIndex(idx)` pair where `idx` is the replica-identity index of a branch table. This covers the second flavor of the bug: when both main and branch already point at the same replica-identity index, but that index's _definition_ changes (e.g. a column added to its key), the index is replaced, Postgres silently flips `relreplident` to `'d'`, and the table-level diff alone cannot see the cross-object interaction. The pass is idempotent — if `diffTables()` already emitted the same setter (because the table is also flipping mode or pointing to a different index), no duplicate is added. - - The post-diff layer file `src/core/post-diff-cycle-breaking.ts` is renamed to `post-diff-normalization.ts` and `normalizePostDiffCycles` to `normalizePostDiffChanges` — the file already contained dedup and replacement-superseded pruning that aren't strictly cycle-breaking, and actual cycle breaking moved to the lazy sort-phase dispatcher in a previous release. The rename brings the file in line with the "post-diff normalization" terminology already used in the package's `CLAUDE.md` rule of thumb. - -- 2d1991a: fix(pg-delta): skip table constraints where `pg_get_constraintdef()` returns NULL instead of crashing `extractTables` with a ZodError. Like `pg_get_indexdef`, `pg_get_constraintdef` can return NULL under race conditions with concurrent DDL or transient catalog inconsistencies. Such constraints are now filtered out at extraction time so a single unreadable constraint no longer aborts the whole catalog extraction and `createPlan` call. - -## 1.0.0-alpha.21 - -### Patch Changes - -- fa3f736: fix(pg-delta): emit USING and default-safe flow for ALTER COLUMN TYPE -- 363fef3: Fix ZodError when extracting tables with EXCLUDE constraints defined over expressions. PostgreSQL stores `attnum=0` in `pg_constraint.conkey` for expression elements, which never matches `pg_attribute`, so the inner aggregate returned SQL `NULL` and tripped `tablePropsSchema` at `constraints[*].key_columns`. The extractor now coalesces the aggregate to an empty JSON array. -- cbe8946: Defer drop-phase cycle breaking from `normalizePostDiffCycles` to a lazy - dispatcher invoked by `sortPhaseChanges` only when edge filtering can't - break a cycle. The happy path (no cycles, the vast majority of plans) no - longer walks `iterCrossDropFkConstraints` on every diff. The new - dispatcher generalizes the existing 2-cycle FK breaker to any - N≥2 strongly-connected component of dropped tables (for example - `a→b→c→a`) and breaks the - `AlterPublicationDropTables ↔ AlterTableDropColumn` cycle that occurred - when a publication-listed column was dropped on a surviving table. The - breaker round-cap scales with `phaseChanges.length` so big diffs with - many independent unbreakable cycles in a single phase resolve cleanly - instead of throwing a spurious `CycleError`. - - The sequence diff path now alters `data_type` in place via - `ALTER SEQUENCE ... AS ` (valid PostgreSQL since PG10) instead of - emitting `DROP SEQUENCE + CREATE SEQUENCE`. This eliminates a - production `CycleError` seen on alpha.16 (Sentry SUPABASE-API-7RS, - "DropSequence ↔ DropTable") triggered when a sequence whose - `data_type` changes is referenced by a `DEFAULT nextval(...)` on a - surviving column. Altering in place also fixes a silent data-loss - regression where the recreated sequence would restart at `1` and - collide with existing row ids. - -## 1.0.0-alpha.20 - -### Patch Changes - -- ac7b9b8: fix(pg-delta): skip `WITH SCHEMA` when serializing `pgsodium` and `pg_tle` under the Supabase integration - - Both extensions create their install schema (`pgsodium`, `pgtle`) themselves, and those schemas are filtered out of the declarative plan by the Supabase integration because they live in `SUPABASE_SYSTEM_SCHEMAS`. Emitting `CREATE EXTENSION pgsodium WITH SCHEMA pgsodium` (or the equivalent for `pg_tle`) therefore fails against a fresh database with `schema "pgsodium" does not exist` — the same bug shape PR #191 fixed for `pgmq`. - - Closes supabase/pg-toolbelt#222. - -## 1.0.0-alpha.19 - -### Patch Changes - -- 4867d88: Handle dependent index and view recreation when replacing a materialized view. Constraint-owned, primary, and partition-attached indexes are left to the owning constraint or parent-index DDL so table replacement does not emit a standalone `DROP INDEX` on a PK-owned index. -- f00e9a4: fix(pg-delta): skip indexes where `pg_get_indexdef()` returns NULL instead of crashing `extractIndexes` with a ZodError. The three-argument form of `pg_get_indexdef` can return NULL under race conditions with concurrent DDL (e.g. the index being dropped mid-extraction) or when catalog metadata is transiently inconsistent. Such indexes are now filtered out with a debug log (`DEBUG=pg-delta:extract:index`) so a single unreadable index no longer aborts the whole catalog extraction and `createPlan` call. -- f33d579: fix(pg-delta): order RLS policies after referenced new objects - - Policies whose `USING` / `WITH CHECK` expression references another new object could be emitted before the referenced object on a fresh database, causing plan/apply to fail. - - `extractRlsPolicies` now joins `pg_depend` to surface every relation (tables, partitioned tables, views, materialized views, foreign tables) and function the policy expression references. PostgreSQL already records those edges at `CREATE POLICY` time via `recordDependencyOnExpr`, so the catalog is authoritative and pg-delta's core diffing path does not reparse the expression text. `CreateRlsPolicy.requires` dispatches per relation kind and emits `stableId.procedure(...)` for functions, using the exact argument signature produced by `format_type(proargtypes)` — matching the signature embedded in the procedure extractor's stable id. - - Sequences referenced via `nextval('seq'::regclass)` remain a known gap (tracked as a skipped regression test) because `pg_depend` only records the edge for `regclass` literal arguments. - -## 1.0.0-alpha.18 - -### Patch Changes - -- feca870: fix(pg-delta): diff PostgreSQL 18 temporal constraints -- b812a46: fix(pg-delta): emit DROP + CREATE for function signature changes (return type, parameter names, parameter defaults, modes) instead of unsupported `CREATE OR REPLACE FUNCTION` -- feca870: fix(pg-delta): dedupe duplicate constraint ADDs on tables promoted to drop+create - - When a table transitively depends on a replaced object (for example a - foreign key whose referenced primary key is being dropped and re-added to - flip to `WITHOUT OVERLAPS` / `PERIOD`), `expandReplaceDependencies()` - promotes the table to a full `DropTable + CreateTable` pair and emits one - `AlterTableAddConstraint` (plus optional `VALIDATE CONSTRAINT` / - `COMMENT ON CONSTRAINT`) per branch constraint. The original - `diffTables()`-emitted `AlterTableAddConstraint` targeting the same - constraint on the same replaced table was previously left in the plan, - producing duplicate `ALTER TABLE ... ADD CONSTRAINT` statements and a - `constraint "..." for relation "..." already exists` apply failure. - - `normalizePostDiffCycles()` now dedupes same-table - `AlterTableAddConstraint`, `AlterTableValidateConstraint` and - `CreateCommentOnConstraint` changes keyed by - `(changeType, table.stableId, constraint.name)` on replaced tables, - keeping only the last occurrence. Because `expandReplaceDependencies()` - appends its additions after the original `diffTables()` output, the last - occurrence is always the expansion's emission — so correctness is - preserved while the earlier duplicate is removed. This fixes migrations - that combine a temporal-PK flip on one table with a temporal-FK flip on a - related table without regressing unrelated replace-expansion scenarios - (enum value removal, table replacement via other object replacements). - -## 1.0.0-alpha.17 - -### Patch Changes - -- 5cc2a21: fix(pg-delta): stop emitting spurious `CREATE OR REPLACE TRIGGER` on logically-identical triggers whose underlying tables have different physical column layouts. - - The trigger diff was comparing `pg_trigger.tgattr` (raw physical attnums) as part of its non-alterable fields. When the same logical trigger (e.g. `BEFORE UPDATE OF col_a, col_b ...`) existed on two tables with different physical column layouts — one built via a single `CREATE TABLE`, the other grown via `ALTER TABLE DROP/ADD COLUMN` (which leaves "dead" attnums that are never renumbered) — the attnum vectors diverged while the trigger definition (rendered by `pg_get_triggerdef()` using column names) was byte-identical. The diff kept firing a `ReplaceTrigger` every round, and because `CREATE OR REPLACE TRIGGER` does not renumber the table's physical columns, the loop never converged. - - Triggers are now compared by `pg_get_triggerdef()` output (column names) instead of raw `tgattr` attnums, matching the existing `Index` pattern that handles the same class of bug for `indkey`. - -## 1.0.0-alpha.16 - -### Patch Changes - -- a0f6f11: fix(pg-delta): strip brackets from IPv6 hosts before handing them to pg so `getaddrinfo` sees a bare address. - - The alpha.14 IPv6 fix normalized percent-encoded hosts into the canonical bracketed URL form (`postgresql://user@[2600:...]:5432/db`). That is a valid URL, but `pg-connection-string`'s WHATWG-based parser keeps the brackets on `config.host`, so `pg` passed `[2600:...]` verbatim to `getaddrinfo` and connections failed with `ENOTFOUND [2600:...]`. - - `createManagedPool` now expands bracketed-IPv6 URLs into explicit `host` / `port` / `user` / `password` / `database` pool fields (plus any remaining query params like `application_name`) and drops `connectionString` on that path — `pg` merges a parsed `connectionString` on top of user config, so a co-provided `host` would otherwise be clobbered. Non-IPv6 URLs still go through `connectionString` unchanged. - -## 1.0.0-alpha.15 - -### Patch Changes - -- 82be5f4: fix(pg-delta): break drop-phase cycles for owned-sequence column drops and replace-dependency table recreates - - Two previously unbreakable drop-phase `CycleError`s are now fixed at the - source by eliding redundant changes instead of patching the sort-phase - cycle filter. - - - `diffSequences` now skips `DROP SEQUENCE` when the owning column is - dropped on a surviving table (e.g. dropping a `SERIAL` column). - PostgreSQL's `OWNED BY` cascade already drops the sequence with the - column, so emitting `DROP SEQUENCE` both failed at apply time and formed - an unbreakable cycle with `AlterTableDropColumn`. This mirrors the - existing short-circuit for whole-table drops. - - `expandReplaceDependencies` now removes pre-existing - `AlterTableDropColumn(T.col)` and `AlterTableDropConstraint(T.c)` changes - when it enqueues a `DropTable(T) + CreateTable(T)` replacement pair for - the same table. Those are the only `AlterTable*` subclasses whose - `requires` includes `table.stableId`, producing a `column:T.col → table:T` - (or `constraint:T.c → table:T`) explicit edge that closed an unbreakable - drop-phase cycle against catalog `constraint → column → table` edges. - Supersession is scoped to those two classes only; other `AlterTable*(T)` - changes (owner, RLS toggles, replica identity, storage params, - SET LOGGED/UNLOGGED) and privilege-scope ALTERs (GRANT/REVOKE) are - preserved so the recreated table ends up in the correct state — the sort - phase orders them after `CreateTable(T)` via their `table.stableId` - requirement. - -- 82be5f4: fix(pg-delta): break drop-phase cycle when two tables have mutual FK references - - Previously, diffing two databases where two tables each hold a foreign key - pointing at the other (and both tables are being dropped) produced a - `CycleError` because both `DropTable` changes claimed the other's FK - constraint stableId, creating bidirectional catalog edges in the drop-phase - graph. Even if the cycle had been broken at the sort layer, plain - `DROP TABLE` would have failed at apply time because PostgreSQL refuses to - drop a table while another table still has an FK pointing to it. - - The diff layer now detects mutual FK references between tables dropped in - the same phase and emits explicit `ALTER TABLE ... DROP CONSTRAINT ...` - statements before the `DROP TABLE`s, producing a safe linear sequence and - no cycle in the drop-phase graph. - -## 1.0.0-alpha.14 - -### Patch Changes - -- 13e94b9: fix(pg-delta): auto-normalize percent-encoded IPv6 hosts in connection URLs and retry transient connect failures. - - Connection strings with URL-encoded IPv6 hosts (e.g. `postgresql://user:pass@2406%3Ada18%3A...%3Ab3c9:5432/db`) are now transparently rewritten to the canonical bracketed form (`[2406:da18:...:b3c9]`) before reaching `pg`, preventing `getaddrinfo ENOTFOUND` failures on the percent-encoded string.

If a single object diff can prove a statement is redundant or invalid on its own, fix it there. Example: `src/core/objects/sequence/sequence.diff.ts` skips `DROP SEQUENCE` when `OWNED BY` means PostgreSQL will already cascade-drop it with the owning table/column. -- **Deterministic whole-plan rewrites belong in post-diff normalization**. If the final `Change[]` itself should be rewritten before dependency sorting, implement it in `src/core/post-diff-normalization.ts` (`normalizePostDiffChanges`), wired from `src/core/catalog.diff.ts` after raw diffs and `expandReplaceDependencies()`. The pass is the single chokepoint that observes the final `Change[]`, so it catches cross-object effects regardless of whether the relevant change pair was emitted by an object's `diff*` (e.g. `index.diff` for a definition-changed index) or by `expandReplaceDependencies()` (dependency-closure replacement). Current examples: pruning same-table `AlterTableDropColumn` / `AlterTableDropConstraint` changes superseded by an expansion-added `DropTable+CreateTable` pair, deduplicating constraint Add/Validate/Comment on replaced tables, and re-emitting `ALTER TABLE … REPLICA IDENTITY USING INDEX` after a replica-identity index is dropped+recreated. -- **Unbreakable graph cycles belong in sort-phase change injection**. If the emitted statements are valid but topological sorting discovers a hard dependency cycle that cannot be solved by weak-edge filtering, implement the narrow pattern in `src/core/sort/cycle-breakers.ts` (`tryBreakCycleByChangeInjection`). Existing examples: injecting explicit FK constraint drops for dropped-table FK cycles and rebuilding `AlterTableDropColumn` for publication-column cycles on surviving tables. -- **`expandReplaceDependencies()` only computes replacement closure**. It may report metadata such as which tables were promoted to replacement pairs, but it should not own unrelated cycle-pruning policy. -- **`src/core/sort/dependency-filter.ts` is a narrow last resort**. Use it only for safe edge filtering where the emitted statements are already valid and only the graph edge is artificial. Do not extend sort-phase filtering to paper over plans that would still fail at apply time. -- **In-place mutations that invalidate dependents declare `invalidates`, not a graph hack**. When a change keeps an object's identity but rewrites it so dependents bound to the old definition must be dropped before it and rebuilt after (the canonical case is `AlterTableAlterColumnType`, whose `ALTER COLUMN ... TYPE` forces a PostgreSQL table rewrite), override the `invalidates` getter on the change (sibling to `creates`/`drops`/`requires` in `base.change.ts`) to return the affected stable id. `buildGraphData` folds `invalidates` into the drop-phase producer set exactly like `drops`, so the existing `pg_depend` edges order each dependent's teardown ahead of the mutation. This is ordering-only: `invalidates` does not feed `Change.drops`, so phase assignment (`getExecutionPhase`), filtering, fingerprints, and serialization are unchanged, and recreation order needs no help because the create phase always runs after the entire drop phase. Prefer this over adding a change-type `instanceof` to the otherwise generic `graph-builder.ts`. - -Rule of thumb: if the fix changes a valid final `Change[]` before graph construction, it is post-diff; if it reacts to a concrete unbreakable dependency cycle and needs to inject or rebuild changes, it belongs in the sort-phase cycle breakers; if it needs only one object's semantics, it belongs in that object's `diff*`; if it only removes a graph edge without changing emitted SQL, it belongs in the sort filter; if a change mutates an object in place such that its dependents must be torn down first, it declares `invalidates`. - -### Execution model invariants - -A plan is an ordered list of `MigrationUnit`s (`src/core/plan/types.ts`), each with an explicit `transactionMode` and boundary `reason`, plus session-level statements applied once per session. `plan.units` + `plan.sessionStatements` are the **single execution source of truth** — there is no flat statement list on the plan; render via `renderPlanSql`/`renderPlanFiles` or flatten via `flattenPlanStatements`. Apply counts and messaging derive from units. Rendered scripts (`renderPlanSql`/`renderPlanFiles`) are for statement-splitting runners like `psql -f`; a plan containing a `"none"` unit can never run as a single multi-command query string (PostgreSQL wraps those in an implicit transaction block), which is why such units carry a run-statement-by-statement header instead of any SET/COMMIT reshuffling. - -Execution semantics are declared on the change classes (`base.change.ts`), **never inferred from rendered SQL** — no regex or string matching over serialized statements, ever (a sibling rule to the no-SQL-parsing rule for the plan path): - -- **A statement PostgreSQL rejects inside a transaction block** (SQLSTATE 25001) declares `get nonTransactional(): boolean` on its change class. The planner emits it as its own single-statement unit with `transactionMode: "none"`, and `applyPlan` runs it without `BEGIN`/`COMMIT`. Current cases: `AlterSubscriptionSetPublication` (when `enabled` keeps the `refresh = true` default), `DropSubscription` (when a replication slot is associated). `CreateSubscription` is deliberately NOT one: the 25001 gate is on `create_slot = true` (verified empirically on PG 17), and its serializer always emits `create_slot = false` — with `connect = true` when the slot already exists so it is reused, never recreated. If pg-delta later emits `CREATE INDEX CONCURRENTLY`, subscription `two_phase` alterations, or `ALTER SUBSCRIPTION ... REFRESH PUBLICATION`, those change classes must declare the trait too. -- **A statement whose effects only become usable after COMMIT** declares `get commitBoundary(): CommitBoundaryReason | null`. The canonical case is `AlterEnumAddValue` (55P04). The boundary rule is deliberately conservative: consecutive producers of the same kind share a unit; the next statement of any other kind starts a new unit whose `reason` is the producer's token. No consumer detection is attempted — correctness must not depend on enumerating reference sites. Adding a new kind = one getter override + one member in `CommitBoundaryReason` + one arm in `unitName` (`src/core/plan/render.ts`); the planner fold, render, and apply need no changes. - -## Key Concepts - -### Change object structure - -Every change has: **type**, **operation** (create/alter/drop), **scope** (object/comment/privilege/membership), **properties**, **serialize()**, and **depends** (array of stable identifiers). - -### Stable identifiers - -Used to track objects across databases (OIDs differ per environment): - -- Schema objects: `type:schema.name` (e.g. `table:public.users`). -- Sub-entities: `type:schema.parent.name` (e.g. `column:public.users.email`). -- Metadata: `scope:target` (e.g. `comment:public.users`). - -**Always build stable identifiers through the `stableId.*` helpers in -`src/core/objects/utils.ts` (or the `.stableId` getter on a model -instance) — never inline the prefix as a template literal.** Inline strings -like `` `index:${schema}.${table}.${name}` `` drift from the helper if -prefixes or escaping rules change, scatter the format across the codebase, -and were caught in review on this exact pattern. If you need a stable id -for an object type that does not have a helper yet, add the helper to -`stableId` first, then use it everywhere — including new code paths, -post-diff passes, and dependency wiring inside change classes. - -When asserting stable ids in tests, the literal form is fine as the -expected value (it documents the on-the-wire format), but the **production -side** of the comparison should still call the helper. - -### Integration DSL - -- **Filter**: JSON pattern to include/exclude changes (e.g. `{ "not": { "schema": ["pg_catalog"] } }`). -- **Serialize**: Rules to customize SQL (e.g. `skipAuthorization` for schema create). - -## Working with Database Objects - -To add a new PostgreSQL object type: - -1. Create `src/core/objects//` with `.model.ts` and `.diff.ts`. -2. Add change classes in `changes/` (create, alter, drop, comment, privilege as needed). -3. Register in `catalog.model.ts` (Catalog type + extractor). -4. Register in `catalog.diff.ts` (diff function in `diffCatalogs`). - -### Physical attnums vs logical names - -Never place raw PostgreSQL attnums (`pg_trigger.tgattr`, `pg_index.indkey`, `pg_constraint.conkey`/`confkey`, `pg_publication_rel.prattrs`, etc.) inside a model's `dataFields()` or `NON_ALTERABLE_FIELDS`. Attnums are **physical** and diverge between logically-identical tables whose column layouts were built differently (`CREATE TABLE` vs `ALTER TABLE DROP/ADD COLUMN`) — dropped columns leave "dead" attnums that are never renumbered, so every subsequent diff would emit a spurious replace and never converge. Compare either: - -- the authoritative `pg_get_def()` output (see `Index` and `Trigger`), or -- column **names** resolved via `pg_attribute` at extraction time (see `Table.conkey`/`confkey`, `Publication.prattrs`). - -Storing the raw attnum array purely for debugging/introspection is fine — just keep it out of equality. - -## Conventions - -- TypeScript strict; oxfmt + oxlint for format/lint; kebab-case files with `.model.ts`, `.diff.ts`, `.test.ts`. -- SQL via `@ts-safeql/sql-tag`. - -## Dependencies & Debug - -- **Runtime**: `pg`, `@stricli/core`, `@ts-safeql/sql-tag`, `zod`, `debug`. -- **Debug**: `DEBUG=pg-delta:* bun run pgdelta ...`; for declarative apply, `DEBUG=pg-delta:declarative-apply` (or `DEBUG=pg-delta:*`) shows deferred statements and per-round summaries. diff --git a/packages/pg-delta-next/COVERAGE.md b/packages/pg-delta/COVERAGE.md similarity index 100% rename from packages/pg-delta-next/COVERAGE.md rename to packages/pg-delta/COVERAGE.md diff --git a/packages/pg-delta-next/MIGRATION.md b/packages/pg-delta/MIGRATION.md similarity index 100% rename from packages/pg-delta-next/MIGRATION.md rename to packages/pg-delta/MIGRATION.md diff --git a/packages/pg-delta/README.md b/packages/pg-delta/README.md index 8b97c8a82..9c4bba327 100644 --- a/packages/pg-delta/README.md +++ b/packages/pg-delta/README.md @@ -1,194 +1,202 @@ -# pg-delta +# @supabase/pg-delta-next -PostgreSQL migrations made easy. +Clean-room rebuild of pg-delta per [`docs/architecture/target-architecture.md`](../../docs/architecture/target-architecture.md) +(see [the build log](../../docs/build-log.md) for how it was built, stage by +stage). **Working name** — final naming is a stage-10 product decision.

Integrations - -```typescript -import { supabase } from "@supabase/pg-delta/integrations/supabase"; -``` - -## Functions - -### `createPlan(source, target, options?)` - -Create a migration plan by comparing two databases. - -#### Parameters - -- `source` (string | Sql): Source database connection URL or postgres.js client (current state) -- `target` (string | Sql): Target database connection URL or postgres.js client (desired state) -- `options` (CreatePlanOptions, optional): Configuration options - -#### Returns - -`Promise<{ plan: Plan; sortedChanges: Change[]; ctx: DiffContext } | null>` - -- Returns an object with the plan and metadata if there are changes -- Returns `null` if databases are identical -- Throws `UnorderableCycleError` when the changes contain a dependency cycle that cannot be ordered; `error.cycle` carries the offending changes - -#### Example - -```typescript -import { createPlan } from "@supabase/pg-delta"; - -const result = await createPlan( - process.env.SOURCE_DB_URL!, - process.env.TARGET_DB_URL! -); - -if (result) { - console.log(`Found ${result.plan.units.length} migration units`); - console.log(renderPlanSql(result.plan)); -} else { - console.log("No differences found"); -} -``` - ---- - -### `applyPlan(plan, source, target, options?)` - -Apply a plan's migration units to a database with integrity checks. Validates fingerprints before and after application to ensure plan integrity. - -Units are applied in order on a single session: transactional units inside an explicit `BEGIN`/`COMMIT`, non-transactional units without a wrapper. Multi-unit plans are therefore **not atomic as a whole** — a failure in a later unit does not roll back units that already committed. - -#### Parameters - -- `plan` (Plan): The migration plan to apply -- `source` (string | Sql): Source database connection URL or postgres.js client -- `target` (string | Sql): Target database connection URL or postgres.js client -- `options` (ApplyPlanOptions, optional): Configuration options - - `verifyPostApply` (boolean, default: true): Verify fingerprint after applying - -#### Returns - -`Promise` - -The result is a discriminated union with the following possible statuses: - -```typescript -type ApplyPlanResult = - | { status: "invalid_plan"; message: string } - | { status: "fingerprint_mismatch"; current: string; expected: string } - | { status: "already_applied" } - | { status: "applied"; statements: number; units: number; warnings?: string[] } - | { - status: "failed"; - error: unknown; - script: string; - /** 0-based index of the unit that failed; undefined if a session statement failed. */ - failedUnitIndex?: number; - /** Number of units fully committed before the failure. */ - completedUnits: number; - }; -``` - -#### Example - -```typescript -import { createPlan, applyPlan } from "@supabase/pg-delta"; - -const result = await createPlan(sourceUrl, targetUrl); - -if (result) { - const applyResult = await applyPlan(result.plan, sourceUrl, targetUrl); - - switch (applyResult.status) { - case "applied": - console.log( - `Applied ${applyResult.statements} statements across ${applyResult.units} units`, - ); - break; - case "already_applied": - console.log("Plan already applied"); - break; - case "fingerprint_mismatch": - console.error("Source database has changed since plan was created"); - break; - case "failed": - console.error("Failed to apply:", applyResult.error); - break; - } -} -``` - -## Types - -### `Plan` - -A migration plan containing all changes to transform one database schema into another, as an ordered list of execution-aware migration units. - -```typescript -interface Plan { - version: number; // 2 - toolVersion?: string; - source: { fingerprint: string }; - target: { fingerprint: string }; - units: MigrationUnit[]; - sessionStatements: string[]; // SET ROLE, ... applied once per session - role?: string; - filter?: FilterDSL; - serialize?: SerializeDSL; - risk?: { level: "safe" } | { level: "data_loss"; statements: string[] }; -} - -interface MigrationUnit { - transactionMode: "transactional" | "none"; - reason: "default" | "enum_value_visibility" | "non_transactional"; - statements: string[]; -} -``` - -A plan needs more than one unit when a statement's effects only become usable after COMMIT (e.g. `ALTER TYPE ... ADD VALUE`, whose new value cannot be referenced in the same transaction — PostgreSQL error 55P04), or when a statement cannot run inside a transaction block at all (e.g. `DROP SUBSCRIPTION` with an associated replication slot). - -Render a plan with `renderPlanSql(plan)` (single script) or `renderPlanFiles(plan)` (one numbered file per unit, as written by `pgdelta plan --output-dir`). `flattenPlanStatements(plan)` returns the raw ordered statements (session statements included) when transaction context does not matter. - -**Execution contract for rendered SQL:** run scripts with a statement-splitting runner such as `psql -f` (each statement is sent separately, so session `SET`s apply and non-transactional units execute outside any transaction). Do not execute a rendered script as a single multi-statement query string (node-postgres `query(file)`, `PQexec`) and do not use `psql --single-transaction`: PostgreSQL runs every statement of a multi-command string in an implicit transaction block, so any `transactionMode: "none"` unit would fail with 25001 regardless of statement ordering. For programmatic application use `applyPlan`, which executes statement-by-statement on a single session. - -Legacy v1 plan JSON (flat `statements` array) is still accepted by `deserializePlan`/`applyPlan` and is normalized into a single transactional unit. - -### `CreatePlanOptions` - -Options for creating a plan. - -```typescript -interface CreatePlanOptions { - /** Filter - either FilterDSL (stored in plan) or ChangeFilter function (not stored) */ - filter?: FilterDSL | ChangeFilter; - /** Serialize - either SerializeDSL (stored in plan) or ChangeSerializer function (not stored) */ - serialize?: SerializeDSL | ChangeSerializer; - /** Role to use when executing the migration (SET ROLE will be added to statements) */ - role?: string; -} -``` - -### `IntegrationDSL` - -A serializable representation of an integration combining filter and serialization options. - -```typescript -type IntegrationDSL = { - /** Filter DSL - determines which changes to include/exclude */ - filter?: FilterDSL; - /** Serialization DSL - customizes how changes are serialized */ - serialize?: SerializeDSL; -}; -``` - -See [Integrations](./integrations.md) for the full DSL documentation. - -## Using Integrations - -Integrations provide pre-configured filter and serialize options. Use them by spreading their properties into `CreatePlanOptions`: - -```typescript -import { createPlan } from "@supabase/pg-delta"; -import { supabase } from "@supabase/pg-delta/integrations/supabase"; - -// Use the supabase integration -const result = await createPlan(sourceUrl, targetUrl, { - filter: supabase.filter, - serialize: supabase.serialize, -}); -``` - -### Custom Integration - -You can create your own integration using the `IntegrationDSL` type: - -```typescript -import { createPlan, type IntegrationDSL } from "@supabase/pg-delta"; - -const myIntegration: IntegrationDSL = { - filter: { - schema: "public", - }, - serialize: [ - { - when: { type: "schema", operation: "create" }, - options: { skipAuthorization: true }, - }, - ], -}; - -const result = await createPlan(sourceUrl, targetUrl, { - filter: myIntegration.filter, - serialize: myIntegration.serialize, -}); -``` - -## Error Handling - -Both `createPlan` and `applyPlan` may throw errors for connection failures or database query errors. Always wrap calls in try-catch blocks: - -```typescript -try { - const result = await createPlan(sourceUrl, targetUrl); - // Handle result -} catch (error) { - console.error("Failed to create plan:", error); - process.exit(1); -} -``` - -## Examples - -### Basic Migration - -```typescript -import { createPlan, applyPlan } from "@supabase/pg-delta"; - -async function migrate() { - const sourceUrl = process.env.SOURCE_DB_URL!; - const targetUrl = process.env.TARGET_DB_URL!; - - const result = await createPlan(sourceUrl, targetUrl); - - if (!result) { - console.log("No differences found"); - return; - } - - console.log("Migration plan:"); - console.log(result.plan.statements.join(";\n")); - - const applyResult = await applyPlan(result.plan, sourceUrl, targetUrl); - - if (applyResult.status === "applied") { - console.log(`Successfully applied ${applyResult.statements} statements`); - } -} -``` - -### With Supabase Integration - -```typescript -import { createPlan, applyPlan, renderPlanSql } from "@supabase/pg-delta"; -import { supabase } from "@supabase/pg-delta/integrations/supabase"; - -const result = await createPlan(sourceUrl, targetUrl, { - filter: supabase.filter, - serialize: supabase.serialize, -}); - -if (result) { - await applyPlan(result.plan, sourceUrl, targetUrl); -} -``` - -### With Role - -```typescript -import { createPlan } from "@supabase/pg-delta"; - -// SET ROLE will be added to the beginning of the migration -const result = await createPlan(sourceUrl, targetUrl, { - role: "postgres", -}); -``` - -### Filtering by Schema - -```typescript -import { createPlan } from "@supabase/pg-delta"; - -// Only include changes in the public schema -const result = await createPlan(sourceUrl, targetUrl, { - filter: { schema: "public" }, -}); -``` diff --git a/packages/pg-delta/docs/cli.md b/packages/pg-delta/docs/cli.md deleted file mode 100644 index 2b05a3ee0..000000000 --- a/packages/pg-delta/docs/cli.md +++ /dev/null @@ -1,435 +0,0 @@ -# CLI Reference - -The `pg-delta` CLI provides a command-line interface for managing PostgreSQL schemas.

Collapse them into a single major @supabase/pg-delta "clean-room rewrite" changeset that summarizes the substance (proof loop, redesigned CLI/API, schema export/apply, profiles, ADP/owner-ACL correctness, formatting, redaction, PG14-18). The genuine @supabase/pg-topo bump (pg-topo-total-ordered) is preserved as its own entry. Also relink bun.lock for the @supabase/pg-delta-next -> @supabase/pg-delta workspace rename. Verified: `changeset status` reports @supabase/pg-delta major + @supabase/pg-topo minor with no unknown-package error; a throwaway `changeset version` bumped pg-delta to 1.0.0-alpha.32 and was reverted.

Replace it with the new engine's testcontainers-based jobs, folded into tests.yml and gated on the existing pg-delta paths-filter: - pg-delta-unit: `bun test src/`. - pg-delta-corpus: PG 14-18 x 4 shards, the proof loop (engine.test.ts), keyed on PGDELTA_TEST_IMAGE + PGDELTA_NEXT_SHARD. - pg-delta-integration: PG 14-18, all tests except the corpus loop. - Keep pg-delta-integration-pg15/17-compat aggregator names for stable branch-protection checks (now validating corpus + integration). - check-types now builds @supabase/pg-topo first (pg-delta type-checks its optional peer through dist/*.d.ts). - Delete .github/workflows/pg-delta-next.yml (folded in). - Drop pg-delta Istanbul coverage upload (the new engine has none wired; coverage report is now pg-topo only). Follow-up tracks re-wiring. - Point the Deno golden-path fixture at @supabase/pg-delta/sql-format (formatSqlStatements moved off the root export). Verified: the full deno-library-e2e (build + npm pack + Deno import) passes locally. - Remove the dead root `docs:pg-delta` script (new engine has no typedoc). Branch-protection required-check names may need updating: the removed pg-delta-test-image-hash / pg-delta-build-test-images checks no longer run.

Do not reach into `@supabase/pg-topo` — or any other SQL-parser / AST library — from this path, even as a "best-effort" helper. - -When a change class needs dependency edges for `requires` or `creates`: - -1. **First, check `pg_depend`.** Postgres records expression-level dependencies automatically (policy `USING` / `WITH CHECK` via `recordDependencyOnExpr`, `CHECK` constraints, generated columns, column defaults, view rewrite rules, trigger functions, SQL-language function bodies, sequence ownership, etc.). That catalog is authoritative and already used extensively in `src/core/depend.ts`; extend it instead of inventing a second source of truth. -2. **Source the list at extract time.** Join `pg_depend` in the object's extractor (`.model.ts`) so the resolved schema+name (or stable-id) list is carried on the model. The change class then iterates that list in `requires` — no parsing happens while diffing. -3. **Keep derived metadata out of `dataFields`.** Fields populated from `pg_depend` change lockstep with their source expression (`using_expression`, `with_check_expression`, etc.), so including them in equality adds no signal and creates noisy diffs. -4. **Don't re-parse what Postgres already parsed.** Re-parsing `pg_get_expr()` output with an external AST library to recover references is a sign you missed a `pg_depend` row. Find it. - -`pg-topo` is fine as a **dev-time** utility inside pg-delta — for example, `src/core/test-utils/assert-valid-sql.ts` uses `validateSqlSyntax` to sanity-check serialized DDL in unit tests. That usage is scoped to tests and does not leak into the diffing path. - -### Serialize Options - -When adding or changing a serialize option in `pg-delta`, keep the typing and ownership split consistent: - -- Define the shared serializer option fields in `packages/pg-delta/src/core/integrations/serialize/serialize.types.ts`. This file is the single source of truth for `SerializeOptions`. -- If an option is only relevant to one change family, derive a local alias from the shared type in `serialize.types.ts` with `Pick<...>` (for example `SchemaSerializeOptions` or `ExtensionSerializeOptions`) instead of creating a new standalone options type. -- Do not define a separate local `SerializeOptions` type in `packages/pg-delta/src/core/integrations/serialize/dsl.ts`.

Use `_options?: SerializeOptions` for unused parameters so the full `Change` union accepts `change.serialize(rule.options)`. -- Keep product-specific serialization behavior in integrations such as `packages/pg-delta/src/core/integrations/supabase.ts` unless the behavior is truly generic for all users. Integration-specific rules belong in the serialize DSL before they belong in core change logic. -- Do not redesign the global serializer options as a union of per-change option types unless the serialize DSL itself is also being redesigned to tie `when` clauses to specific change subtypes. With the current free-form `FilterPattern`, one shared global contract is the intended model. - -When adding a new serialize option, update tests at the same time: - -- Add or update focused coverage in `packages/pg-delta/src/core/integrations/serialize/dsl.test.ts`. -- Add or update the relevant object serializer test next to the concrete change class (for example `extension.create.test.ts`). -- If the behavior is user-facing, update one existing end-to-end regression or add one targeted integration test.

Build pg-topo first, then the rest (`--filter '@supabase/pg-topo' build && --filter '!@supabase/pg-topo' build`). - **dbdev-roundtrip depended on the deleted legacy package.** Its fixture bootstrap reached cross-package into `../../../pg-delta/tests/{utils, supabase-postgres}.ts` and `tests/integration/fixtures/dbdev-migrations/` — all deleted with the old engine (they only resolved while both packages coexisted). Rehome it onto the new package: copy the dbdev migration fixtures to tests/fixtures/dbdev-migrations/, add a standalone Supabase container starter (startStandaloneSupabase) to tests/containers.ts, and use the new applySupabaseBaseInit. Gate the test with describe.skipIf(!runSupabaseBareTests) like the other Supabase-image suites so it runs only on the matching PG leg. Verified: clean `bun run build` succeeds; the rehomed dbdev roundtrip passes end-to-end against supabase/postgres:17 (PGDELTA_NEXT_SUPABASE_TESTS=1); unit suite (666) + check-types + knip green.

A policy-excluded role's owner edge was therefore retained and then auto-assumed in `plan()`, laundering the excluded role back in as `CREATE SCHEMA … AUTHORIZATION ` / `OWNER TO` and silencing the missing-requirement guard. Integration CI on #299 caught it (tests/policy.test.ts) — the focused suites/corpus during development didn't run that file. Invariant fix (view.ts): `excludeFactsAndDescendants` PRESERVES edges already dangling on input (the seed-rebuild fix) but never MINTS a new dangling edge whose endpoint this exclusion removes (`&& !fb.has(e.to)`). Only `projectManagementScope` mints owner dangling edges, via its own edge loop. policy hard-exclusion prunes the excluded role's owner edge again, so the guard fires and the object is created ownerless (owner-edge case (c) behavior). Also: the "typo'd function body is caught by re-validation" test now runs under `strictFunctionBodies: true` (the lenient-bodies change made a user-routine body-lint a warning by default; strict is where re-validation is fatal). RED (before fix): a new no-Docker unit test — plan() with a policy excluding all roles + a kept schema whose USAGE ACL grants to the excluded owner role — did NOT throw and emitted `CREATE SCHEMA "app" AUTHORIZATION "sys"`; owner-edge case (c) leaked `AUTHORIZATION "sys"`. GREEN: guard throws /missing requirement/, no AUTHORIZATION leak. 21 pass across the two integration files, 28 blast-radius, 688 unit, 596/596 corpus (pg17), check-types + format-and-lint clean.

Add a plan-time guard that throws a clear error naming the type + dependent column(s), mirroring the in-use composite-type guard. (Full column migration tracked in #332.) - #5 (non-convergence): a newly-created rewrite rule was left ENABLED, so a disabled/replica/always rule never converged. `rule.create` now appends the `ALTER TABLE … {DISABLE|ENABLE REPLICA|ENABLE ALWAYS} RULE` follow-up when ev_enabled != 'O' (same pattern as trigger rules). - #4 (determinism): the `pg_inherits` parent subquery was `LIMIT 1` with no ORDER BY → nondeterministic captured parent → fact-hash flap. Order by inhseqno. (Full multiple-inheritance support tracked in #332.) - #8 (fidelity): column-level grants (pg_attribute.attacl) were never extracted, so schemas differing only by `GRANT (col) …` hashed equal and exports dropped them. Extract attacl into column-qualified acl facts (acl StableId gains an optional `column`; object-level ids stay byte-identical) and render `GRANT/REVOKE (col)` via the existing ACL machinery. RED (before fix): #2 plan did not throw (emitted DROP/CREATE); #5 proof drift `rule … enabled "O"->"D"`; #8 from-empty export omitted `GRANT SELECT (a) …`. GREEN: 3 new integration tests + a create-disabled-rule corpus scenario; 598/598 corpus (pg17); 688 unit; supabase-image dbdev-roundtrip + phase2b-seed 3/3; check-types + format-and-lint clean. One reported finding (generated-column dependency edges) was a false positive: that handling is present at src/extract/dependencies.ts (shadow-edge onto the column). Composite attr order, storage/compression, full multi-inheritance, and view column comments are tracked in #332.

Restore the throwing contract and finish the principle: no exported command function calls process.exit — usage guards throw UsageError, operation results route through a CliExit carrier, and main() maps error type to exit code (UsageError/SchemaFrontendError -> 2, CliExit -> its code, else 1). CLI-visible exit codes are unchanged. A bunfig [test] preload guard turns any future in-process process.exit into a normal test failure instead of a masked abort. Also stop emitting owner edges to pg_* built-in pseudo-roles (they were always pruned; this kills the recurring pg_database_owner dangling-edge warning).
