E.8. Postgres Pro Standard 12.13.1
Release Date: 2022-11-23
E.8.1. Overview
This release is based on PostgreSQL 12.13 and Postgres Pro Standard 12.12.2. All improvements inherited from PostgreSQL 12.13 are listed in PostgreSQL 12.13 Release Notes. Other major changes and enhancements are as follows:
Added support for Ubuntu 22.10.
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.
Added rum module, which provides RUM index based on GIN, to Postgres Pro Standard.
Added pg_wait_sampling extension for sampling-based statistics of wait events to Postgres Pro Standard. With this extension, you can get an insight into the server activity, including the current wait events for all processes and background workers.
Added the oracle_fdw extension to Windows versions of Postgres Pro.
Upgraded mamonsu to version 3.5.2, which provides new features and bugfixes. Notable changes are as follows:
Added autovacuum utilization metrics.
Added Zabbix macros based on plugin parameters from the configuration file, so that triggers can now be dynamically changed directly in Zabbix without updating the configuration file and restarting mamonsu.
Upgraded pg_probackup to version 2.5.10, which provides optimizations and bugfixes. Notable changes are as follows:
Fixed an issue with
checkdb--amcheck, which previously completed with an error when the checked database contained partitioned indexes.Fixed a backup failure on a replica that occurred because the version of the pg_probackup agent running there was different from that on the master.
Upgraded pgpro_pwr to version 4.1, which mainly adds JIT-related statistics to report tables.
Upgraded pgpro_stats to version 1.4.3, which provides bugfixes. In particular:
Fixed possible server crashes that could occur during query text normalization when an extended protocol was used.
E.8.2. Migration to Version 12.13.1
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.
While functions numeric_eq, numeric_ne, numeric_gt, numeric_ge, numeric_lt, and numeric_le are actually leakproof, they were not marked as such in Postgres Pro Standard 12.1.1, which could lead to incorrect query optimization. In particular, it negatively affected query execution if row-level security policy was in use. Version 12.2.1 repairs this issue for new installations by correcting the initial catalog data, but existing installations will still have incorrect markings unless you update pg_proc entries for these functions. You can run pg_upgrade to upgrade your server instance to a version containing the corrected initial data, or manually correct these entries in each database of the installation using the ALTER FUNCTION command. For example:
ALTER FUNCTION pg_catalog.numeric_eq LEAKPROOF
When upgrading from Postgres Pro versions 12.6.1 or lower, rebuild indexes containing at least one included column of type for which the collation was defined in the table.
If you are upgrading from Postgres Pro versions 12.6.2 or lower and take PTRACK backups using pg_probackup, retake a full backup after upgrade.
