Postgres Pro Standard 15.1.1: release notes

E.1. Postgres Pro Standard 15.1.1

Release Date: 2022-11-25

E.1.1. Overview

This release is based on PostgreSQL 15.1 and Postgres Pro Standard 15.0.1. All improvements inherited from PostgreSQL 15.1 are listed in PostgreSQL 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.

  • Upgraded pg_probackup to version 2.5.10.

E.1.2. Migration to Version 15.1.1

If you are upgrading from Postgres Pro Standard based on the same PostgreSQL major version, it is enough to install the new version into your current installation directory.

To migrate from PostgreSQL or a Postgres Pro Standard release based on a previous PostgreSQL major version, see the instructions in Postgres Pro Standard 15.0.1 Release Notes.
