Percona Distribution for PostgreSQL 17.10.1 ({{date.17_10_1}})

--8<-- "release-notes-intro.md"

This release of Percona Distribution for PostgreSQL is based on Percona Server for PostgreSQL 17.10.1 - a binary compatible, open source drop in replacement of PostgreSQL Community 17.10.

Release Highlights

This release continues to deliver Percona’s open source value-add components for enterprise use cases, including pg_tde 2.2.0 for Transparent Data Encryption and more. See the full component list below for details.

!!! note pg_tde 2.2.0 requires Percona Distribution for PostgreSQL 17.10 at minimum. Earlier versions of PPG are not supported with this release of pg_tde.

To upgrade from earlier versions (e.g. Percona Distribution for PostgreSQL 16.x), follow the steps in Upgrading Percona Distribution for PostgreSQL.

!!! note Starting with this release, shared_preload_libraries is empty by default. Extensions such as pg_tde must be added manually.

Ubuntu 26.04 LTS support added

Percona Distribution for PostgreSQL is available on Ubuntu 26.04 LTS (Noble Numbat's successor). Packages are provided for AMD64 and ARM64 architectures.

Added Quick Start guide

Added a Quick Start Guide walking users through setting up Percona Distribution for PostgreSQL with minimal steps and linking to more advanced topics.

Known Issues

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.

MD5 Authentication Deprecated

The md5 password authentication is deprecated now and will be removed in a future release.
