Percona Distribution for PostgreSQL 15.20 (2026-11-13)

Installation

Percona Distribution for PostgreSQL is a solution that includes PostgreSQL server and the collection of tools from PostgreSQL community. These tools 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 15.20.

Release Highlights

This release continues to deliver Percona’s open source value-add components for enterprise use cases, see the full component list below for details.

Note

To upgrade from earlier versions (e.g. Percona Distribution for PostgreSQL 14.x), follow the steps in Upgrading Percona Distribution for PostgreSQL.

Added credcheck extension

Percona Distribution for PostgreSQL now includes the credcheck extension. credcheck enforces credential policies when users are created, renamed, or change their passwords. For example, it can set minimum password length, require certain character types, block passwords that contain the username, and prevent password reuse.

  • credcheck: 6.0
  • etcd: 3.5.35
  • haproxy: 2.8.31
  • pgaudit_set_user: 4.3.0

Known Issue

For minor & major upgrades (RHEL only)

During an upgrade on RHEL, you may encounter the following error:

Unknown Error occurred: Transaction test error:
  file /usr/share/postgresql-common/server/postgresql.mk from install of percona-postgresql-common conflicts with file from package percona-postgresql-common-dev
  file /usr/share/postgresql-common/t/040_upgrade.t from install of percona-postgresql-common conflicts with file from package percona-postgresql-common-dev

To resolve this, remove the percona-postgresql-common-dev package and reinstall it with the new intended upgraded PPG/PSP server.

On RHEL 10, some earlier releases may have installed the distribution’s PostgreSQL 18 packages, causing the following error:

file /lib/systemd/system/postgresql.service from install of percona-postgresql-common conflicts with file from package postgresql18-server

Warning

Before you remove anything, make sure your database runs on Percona Distribution for PostgreSQL and not on the distribution’s PostgreSQL 18.

To resolve this, remove the distribution’s PostgreSQL packages before upgrading:

sudo dnf remove postgresql18-server postgresql18 postgresql18-private-libs
