Percona Distribution for PostgreSQL 15.19 (2026-08-18)

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 15.19.

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.

  • Fixed an issue where Docker images used a mix of Docker and OCI manifest media types, which prevented pushing the images to OCI-compliant registries. (PKG-1437)

Note

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

Removed dependency on percona-telemetry-agent

The hard depencency on percona-pg-telemetry, which has been a stub since 1.2.0, has been replaced by a weak one and additionally the percona-pg-telemetrypackage no longer installs the telemertry agent (percona-telemetry-agent).

See Telemetry Agent dependencies and removal considerations for details.

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.
