+|:------------------|:-----------------------|
+| **Installation**: | [Installing Percona Distribution for PostgreSQL](installing.md) |
+
+Percona Distribution for PostgreSQL is a solution with the collection of tools from PostgreSQL community that are tested to work together and serve to assist you in deploying and managing PostgreSQL. The aim of Percona Distribution for PostgreSQL is to address the operational issues like High-Availability, Disaster Recovery, Security, Observability, Spatial data handling, Performance and Scalability and others that enterprises are facing.
+
+
+This release of Percona Distribution for PostgreSQL is based on [PostgreSQL 14.9](https://www.postgresql.org/docs/14/release-14-9.html). 
+
+## Release Highlights
+
+* Percona Distribution for PostgreSQL components now include [pg_gather](https://github.com/jobinau/pg_gather) - the open source extension to assess the health of PostgreSQL cluster by gathering performance and configuration data from PostgreSQL databases. This tool helps you run diagnostics of your PosrgreSQL cluster and is also actively used by Percona Support.
+* Percona Distribution for PostgreSQL is now available on Debian 12 (bookworm).
+* The support of Ubuntu 18.04 is deprecated.
+
+------------------------------------------------------------------------------
+

+
+
+Percona Distribution for PostgreSQL also includes the following packages:
+
+* `llvm` 12.0.1 packages for Red Hat Enterprise Linux 8 and derivatives. This fixes compatibility issues with LLVM from upstream.
+* supplemental `ETCD` packages which can be used for setting up Patroni clusters. These packages are available for the following operating systems:
+
+|  Operating system  | Package              | Version | Description        |
+| ------------------ | ---------------------| --------| ------------------ |

+Percona Distribution for PostgreSQL is also shipped with the [libpq](https://www.postgresql.org/docs/14/libpq.html) library. It contains "a set of
+library functions that allow client programs to pass queries to the PostgreSQL
+backend server and to receive the results of these queries."
