Percona Distribution for PostgreSQL 16.8 (2025-02-27)

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 16.7 and PostgreSQL 16.8.

Release Highlights

This release fixes CVE-2025-1094, which closed a vulnerability in the libpq PostgreSQL client library but introduced a regression related to string handling for non-null terminated strings. The error would be visible based on how a PostgreSQL client implemented this behavior. This regression affects versions 17.3, 16.7, 15.11, 14.16, and 13.19. For this reason, version 16.7 was skipped.

Improved security and user experience for Docker images

  • Percona Distribution for PostgreSQL Docker image is now based on Universal Base Image (UBI) version 9, which includes the latest security fixes. This makes the image compliant with the Red Hat certification and ensures the seamless work of containers on Red Hat OpenShift Container Platform.

  • You no longer have to specify the 16.8-multi tag when you run Percona Distribution for PostgreSQL in Docker. Instead, use the percona/percona-distribution-postgresql:16.8. Docker automatically identifies the architecture of your operating system and pulls the corresponding image. Refer to Run in Docker for how to get started.

PostGIS is included into tarballs

We have extended Percona Distribution for PostgreSQL tarballs with PostGIS - an open-source extension to handle spacial data. This way you can install and run PostgreSQL as a geospatial database on hosts without a direct access to the Internet. Learn more about installing from tarballs and Spacial data manipulation
