E.12. Postgres Pro Standard 12.12.2
Release Date: 2022-10-11
E.12.1. Overview
This release is based on Postgres Pro Standard 12.12.1 and provides the following change:
Fixed an issue with queries that could time out due to long lock waits. Previously, index type names were locked in temporary tables during index creation.
E.12.2. Migration to Version 12.12.2
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.
