E.5. Postgres Pro Enterprise 11.19.1
Release date: 2023-03-03
E.5.1. Overview
This release is based on PostgreSQL 11.19 and Postgres Pro Enterprise 11.18.2. All changes inherited from PostgreSQL 11.19 are listed in PostgreSQL 11.19 Release Notes. As compared with Postgres Pro Enterprise 11.18.2, this version also provides the following changes:
Fixed a segmentation fault, which might have occurred in PL/pgSQL when trying to remove a separate field of a composite type upon completion of an autonomous transaction.
Added support for ROSA COBALT Server 7.9 and ended support for ROSA COBALT Server 7.3.
Upgraded pg_probackup to version 2.6.1 Enterprise, which provides the following features:
Optimized pg_probackup input/output engine to improve performance.
Added Simple Storage Service (S3) support for storing data in private clouds. S3 interface was tested with MinIO object storage and VK Cloud storage. Note that pg_probackup provides complete processing of S3 interface logging.
Added CFS (Compressed File System) support for incremental backups in
DELTA,PAGE, andPTRACKmodes.PTRACKmode requires PTRACK 2.4.0 or higher and is recommended as the fastest mode for incremental backups.Added support for zstd compression algorithm.
Ended support for Postgres Pro 9.6.
Upgraded PTRACK to version 2.4.1.
Upgraded pgbouncer to version 1.18.
Upgraded pgpro_scheduler to version 2.9, which provides the following changes:
Fixed the
schedule.resubmitfunction to save the state of the executed job correctly. Also, this function can now accept 0 as the time interval, in this case the job is resubmmitted immediately after execution.Fixed an issue with the
schedule.timetablefunction, which previously caused an error when the function was called by any superuser other thanpostgres.
E.5.2. Migration to Version 11.19.1
If you are upgrading from a Postgres Pro Enterprise release based on the same PostgreSQL major version, it is enough to install the new version into your current installation directory.
Migration of a cluster with tables larger than 16Tb to Postgres Pro Enterprise versions 11 or 10 is not supported.
If you have previously migrated to Postgres Pro Enterprise 11.12.1 or lower, you must run the REINDEX command to rebuild GIN indexes.
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 Enterprise 11.6.1 or lower, which could lead to incorrect query optimization. In particular, it negatively affected query execution if row-level security policy was in use. Version 11.7.1 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
Version 11.7.1 also fixes SIMILAR TO and POSIX regular expressions that use character classes for icu collations, so you may need to check for objects that use such regular expressions.
Starting from Postgres Pro Enterprise 11.6.1, the ICU library upgrade does not interfere with the server start. Before connecting to a database using ICU as the default collation, Postgres Pro compares this collation version to the one provided by the ICU library and displays a warning if the collation versions do not match; you may need to rebuild the objects that depend on the default collation if you think the collation change may affect the sort order of your data. To suppress these warnings, you can use the ALTER COLLATION "default" REFRESH VERSION command, as explained in ALTER COLLATION.
If you are upgrading from Postgres Pro Enterprise versions 11.11.x or lower and take PTRACK backups using pg_probackup, retake a full backup after upgrade.
To migrate from PostgreSQL, as well as Postgres Pro Standard or Postgres Pro Enterprise based on a previous PostgreSQL major version, see the migration instructions for version 11.
