E.24. Postgres Pro Standard 11.5.1
Release Date: 2019-08-09
E.24.1. Overview
This release is based onPostgreSQL 11.5 andPostgres Pro Standard 11.4.1. All improvements inherited fromPostgreSQL 11.5 are listed inPostgreSQL 11.5 Release Notes.
Major enhancements overPostgres Pro Standard 11.4.1 include:
Added support for Debian 10.
Added support for Red Hat Enterprise Linux 8.
Backported an optimization for the
PostmasterIsAlive()check. On Linux systems, backends now use signals to determine that postmaster has died. In particular, it fixes an issue withpg_walbloating and high CPU load when logical replication with multiple publications and subscriptions is used. In vanilla PostgreSQL, this optimization appears in version 12.Improved planning accuracy for queries with
ORclauses. Now sorting is performed correctly for such queries.Fixed implementation of greater than (>) and not equal to (<>) operators for the
jsquerytype.
E.24.2. Migration to Version 11.5.1
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.
Sincepg_probackup delivery model changed inPostgres Pro Standard 11.2.1, when upgrading from a lower version on ALT Linux and Debian-based systems, runapt dist-upgrade (orapt-get dist-upgrade) to ensure that all new dependencies are handled correctly. On Windows, you have to run a separatepg_probackup installer to complete the upgrade.
To migrate fromPostgreSQL or aPostgres Pro Standard release based on a previousPostgreSQL major version, see the instructions inPostgres 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.
