Percona Distribution for PostgreSQL 18.1.1 has been released

We're excited to announce the release of Percona Distribution for PostgreSQL 18.1.1!

Try it out using the Quickstart guide. Check the upgrade instructions.

This release of Percona Distribution for PostgreSQL 18.1.1 provides the following enhancements:

• Parallel logical replication for improved throughput during initial data synchronization
• Faster in-place upgrades via pg_upgrade performance improvements
• Enhanced monitoring with new statistics views for pg_stat_io and background writer activity
• Security improvements, including expanded SSL/TLS configuration options
• Performance optimizations for query execution and index management
• Added support for asynchronous I/O (AIO)

These features make PostgreSQL 18 a major step forward in scalability, observability, and operational efficiency. This release also includes pg_stat_monitor 2.3.1 for advanced query-level observability, pg_tde 2.1 for Transparent Data Encryption and more.

pg_tde is now a standalone package

Starting with PostgreSQL 18, pg_tde is no longer shipped with the server package. If your cluster relies on pg_tde, you must install the package manually.

For more information on the availability by PostgreSQL version, please see the Install pg_tde topic.
