Azure Database for PostgreSQL flexible server: October 2025 Release

We're excited to announce the October 2025 version of Azure Database for PostgreSQL. This version introduces a range of new features and enhancements, resolves known issues, and includes essential security patches to ensure optimal performance and security.

Note

New servers created on or after October 24, 2025, are automatically be onboarded to this latest version. Existing servers will be updated during their next scheduled maintenance. Azure deployments roll out region by region, so availability may vary and the global rollout can take up to one month. Customers should monitor their scheduled maintenance notifications to know when the update will be applied to their server.

Engine version changes

  • No engine version upgrade in this maintenance release.

Features

  • PgBouncer updated from version 1.22 to 1.23. Admin console queries now include extra columns with this update.
  • Citus 13.2 set as the default for PG16 and PG17 for all new Elastic Cluster provisions.
  • Enabled the query store extension for PG18.
  • pg_squeeze extension upgraded to version 1.9, resolving a critical bug in the squeeze.squeeze_table() function that could lead to data corruption.
  • IP4R extension enabled.
  • TimescaleDB extension upgraded to version 2.22.0.

Known issues fixed

  • Fixed an issue that could leave a server in a failed state after a user attempts a Start operation multiple times in a region experiencing capacity constraints. The server is now deallocated in these situations, and a capacity-related error message is returned to the user. This fix now enables users to reattempt Start operations without the server entering a failed state.
