Summary of Changes

Hello @rahulpinto19, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces a fix primarily focused on enhancing the reliability and thoroughness of PostgreSQL test environment cleanup. It streamlines the process by adopting a more aggressive schema reset mechanism and removes an apparently unused or deprecated tool configuration. These changes aim to prevent test flakiness and ensure consistent database states across test runs.

Highlights

• Postgres Test Cleanup Refactor: The CleanupPostgresTables function has been significantly refactored to perform a more robust cleanup. Instead of individually querying and dropping tables, it now drops and recreates the entire public schema, ensuring a completely clean state for subsequent tests.
• Removal of Stored Procedure Tool Kind: The PostgresListStoredProcedureToolKind constant and its associated configuration for the list_stored_procedure tool have been removed from the test setup. This suggests the tool is no longer in use or supported in this context.

🧠 New Feature in Public Preview: You can now enable Memory to help Gemini Code Assist learn from your team's feedback. This makes future code reviews more consistent and personalized to your project's style. Click here to enable Memory in your admin console.

Code Review

This pull request appears to remove the postgres-list-stored-procedure tool and refactors the CleanupPostgresTables test helper function. The changes to remove the tool seem correct based on the provided diff. However, the new implementation of CleanupPostgresTables can be improved. Specifically, it leaves behind a large block of commented-out code that should be removed, and the new logic for cleaning the database schema could be made more robust by executing SQL statements individually for better error handling.

[gemini-code-assist]

This large block of commented-out code from the previous implementation should be removed to improve readability. Git history can be used to review the previous logic if needed.

[gemini-code-assist]

While pgx can execute multiple statements in a single Exec call, it's better practice to execute each statement separately. This improves error handling by pinpointing which statement failed and makes the code easier to read and debug.

	// 1. Drop the entire public schema (this kills tables, views, types, etc.)
	if _, err := pool.Exec(ctx, "DROP SCHEMA public CASCADE;"); err != nil {
		t.Fatalf("Failed to drop public schema: %v", err)
	}

	// 2. Recreate the empty public schema
	if _, err := pool.Exec(ctx, "CREATE SCHEMA public;"); err != nil {
		t.Fatalf("Failed to create public schema: %v", err)
	}

	// 3. Grant permissions back (Postgres default)
	if _, err := pool.Exec(ctx, "GRANT ALL ON SCHEMA public TO public;"); err != nil {
		t.Fatalf("Failed to grant permissions on public schema: %v", err)
	}
