Release Date: 2022-06-07
E.15.1. Overview
This release is based onPostgreSQL 12.11 andPostgres Pro Standard 12.11.1. All improvements inherited fromPostgreSQL 12.11 are listed inPostgreSQL 12.11 Release Notes. Other major changes and enhancements are as follows:
Changed the algorithm of composite type name generation. This fixes an issue in the code of vanillaPostgreSQL, which strictly limits the number of tables with the same long prefix in names.
Upgradedpg_probackup to version 2.5.6, which provides the following new features and bugfixes as compared to version 2.5.5:
Added the
--dry-runflag to thecatchupcommand to allow you to estimate the size of data files to be transferred, but make no changes on disk.Changed the level of detail of logging some
catchupmessages for user convenience of log reading.Fixed a bug that prevented correct rereading of a block after a message“File: ... blknum ... have wrong checksum, try again” was issued.
E.15.2. Migration to Version 12.11.2
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.
While functionsnumeric_eq,numeric_ne,numeric_gt,numeric_ge,numeric_lt, andnumeric_le are actually leakproof, they were not marked as such inPostgres 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 updatepg_proc entries for these functions. You can runpg_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 theALTER FUNCTION command. For example:
ALTER FUNCTION pg_catalog.numeric_eq LEAKPROOF
When upgrading fromPostgres 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 fromPostgres Pro versions 12.6.2 or lower and takePTRACK backups usingpg_probackup, retake a full backup after upgrade.
