E.18. Postgres Pro Standard 14.3.1
Release Date: 2022-05-27
E.18.1. Overview
This release is based on PostgreSQL 14.3 and Postgres Pro Standard 14.2.1. All improvements inherited from PostgreSQL 14.3 are listed in PostgreSQL 14.3 Release Notes. Other major changes and enhancements are as follows:
Fixed a planner issue with self-join removal (SJR) optimization. SJR could do an improper optimization in a corner case when the correctness of the optimization was estimated by scan operator filters “X = const” with a unique column X rather than from the join condition of
JOIN.Ended support for Ubuntu 21.04 and added support for Ubuntu 22.04.
Ended support for OSnova 2.0.
Ended support for GosLinux 7.
Upgraded mamonsu to version 3.4.0. Notable changes are as follows:
Added a new
timeoutparameter to the[zabbix]section of the mamonsu configuration file. It allows you to set maximum time to wait while connecting to the Zabbix server.Added a new
mamonsu dashboard uploadcommand, which can be used to upload a Zabbix dashboard with the mamonsu metrics to a template on the Zabbix server version 6.0 or higher.template_name
Upgraded PTRACK to version 2.3.0, optimizing PTRACK map loading, which previously in some cases could considerably slow down overall database loading. A substantial speed-up is observed for large-size maps.
Upgraded pgpro_stats to version 1.4, which provides the following new features and bugfixes:
Added
pgpro_stats_vacuum_tablesandpgpro_stats_vacuum_indexesviews, which show statistics about vacuuming tables and indexes, respectively. Functions with the same names, which define these views for any specified database and table/index, are also added and can return statistics about vacuuming all tables/indexes in the specified database too.Fixed a bug in extra shared memory allocation. The size of this memory was calculated with an error, which could cause memory corruption, incorrect computation of statistics or even a server crash.
Fixed an issue that caused a server crash when queries that only differ in constants contained in the query text were sent one after another through the extended query protocol.
Upgraded pgpro_pwr to version 3.9, which provides the following new features and bugfixes:
Added statistics on invalidation messages and on vacuuming tables and indexes to the report.
Optimized retention handling for obsolete dictionary entries in the pgpro_pwr historical repository.
Fixed the type of value in calculating the wait time while taking a sample. This prevents a yet unlikely integer overflow error.
