Postgres Pro Standard 13.2.1: release notes


This release is based on PostgreSQL 13.2 and Postgres Pro Standard 13.1.1. All improvements inherited from PostgreSQL 13.2 are listed in PostgreSQL 13.2 Release Notes. Other major changes and enhancements are as follows:

  • Upgraded pgpro_pwr. Major enhancements are as follows:

    • Added export and import functionalities.

    • The collection of relation sizes is now manageable, so that collecting them rarely is possible.

    • Functions support server descriptions.

    • Reporting now supports pg_stat_kcache 2.2.0 and provides more resource usage statistics.


  • Upgraded pg_probackup to the latest version 2.4.10. Major improvements over the previously included version 2.4.2 are as follows:

    • Incremental restore with --force flag now allows you to overwrite the contents of the directory specified by PGDATA in case of system ID mismatch. Previously this resulted in an error.

    • It is now possible to restore and validate backups from a read-only filesystem.

    • In-place merge is now disabled only if the storage format changed.

    • Non-exclusive backup locks are implemented, which enables concurrent validate and restore. Backup shared locks are now released at the process exit.

    • Streamed WAL segments are now added to the backup filelist on the fly and fsynced to disk at the end of the backup.

    See pg_probackup documentation for details.

  • Fixed a bug that prevented setting ptrack.map_size to values higher than 1024 MB due to int32 overflow. See PTRACK for details.

  • Added pgpro_controldata utility to display control information of a PostgreSQL/Postgres Pro database cluster and compatibility information for a cluster and/or server.

  • Added the pg_snapshot_any function to help superusers explore corrupted databases. See Section 9.27.11 for details.

  • Upgraded pgpro_stats. Now it shows resource usage statistics of statement planning and execution, as well as cache invalidation metrics.
