E.23. Postgres Pro Standard 11.5.3
Release Date: 2019-09-16
E.23.1. Overview
This release is based on Postgres Pro Standard 11.5.1 and provides several improvements:
Added support for Python 3 on SLES 12/15 and JIT on SLES 15.
Improved optimizer performance on simple queries.
Fixed assorted bugs in planner that could cause server failures.
E.23.2. Migration to Version 11.5.3
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.
Since pg_probackup delivery model changed in Postgres Pro Standard 11.2.1, when upgrading from a lower version on ALT Linux and Debian-based systems, run apt dist-upgrade (or apt-get dist-upgrade) to ensure that all new dependencies are handled correctly. On Windows, you have to run a separate pg_probackup installer to complete the upgrade.
To migrate from PostgreSQL or a Postgres Pro Standard release based on a previous PostgreSQL major version, see the instructions in Postgres Pro Standard 11.1.1 Release Notes. If you are opting for a dump/restore, make sure to use the --add-collprovider option to correctly choose the provider for the default collation of the migrated database.
