This release is based onPostgreSQL 15.1 andPostgres Pro Standard 15.0.1. All improvements inherited fromPostgreSQL 15.1 are listed inPostgreSQL 15.1 Release Notes. Other major changes and enhancements are as follows:
Fixed huge selectivity overestimation observed in rare cases, which could result in a sequential scan of a whole relation instead of a quick index scan, so certain queries were executed much more slowly than expected. The issue was due to an oversight in a recent optimization of selectivity estimation.
Upgradedpg_probackup to version 2.5.10.
