Release Date: 2021-05-28
E.23.1. Overview
This release is based onPostgreSQL 13.3 andPostgres Pro Standard 13.2.2. All improvements inherited fromPostgreSQL 13.3 are listed inPostgreSQL 13.3 Release Notes. Other major changes and enhancements are as follows:
UpgradedPTRACK to use a different algorithm for tracking changed pages. This greatly reduces the number of false positives among the changed pages tracked in thePTRACK map and hence the size ofPTRACK backups.
Fixed a bug that caused queries to fail with an error“geqo failed to make a valid plan” after updating statistics with
VACUUM ANALYZEwhenenable_compound_index_statswas on.Ended support for Ubuntu 16.04 and added support for Ubuntu 21.04.
Fixed an issue of installingPostgres Pro on Alt Linux 8.2 SP. For this OS,Postgres Pro now provides a separate package repository, which is different from the repositories of earlier Alt Linux SP versions.
Improved the planner's algorithm of self-join selectivity calculation, which ensures more accurate estimates of the number of rows after joins.
Upgradedmamonsu to version 2.7.1.
Upgradedpgpro_controldata to version 13.2.0.
On Windows systems, fixed an issue with updating temporary files for statistics if they are currently in use.

If you are upgrading fromPostgres Pro Standard based on the samePostgreSQL major version, it is enough to install the new version into your current installation directory.
When upgrading fromPostgres Pro versions 13.2.1 or lower, rebuild indexes containing at least one included column of type for which the collation was defined in the table.
If you are upgrading fromPostgres Pro versions 13.2.2 or lower and takePTRACK backups usingpg_probackup, retake a full backup after upgrade.
