This release is based on PostgreSQL 9.6.11 and Postgres Pro Standard 184.108.40.206. All improvements inherited from PostgreSQL 9.6.11 are listed in PostgreSQL 9.6.11 Release Notes.
Major enhancements over Postgres Pro Standard 220.127.116.11 include:
Added support for Ubuntu 18.10, Astra Linux Smolensk 1.6, and Red OS Murom 7 operating systems.
Improved plantuner stability and fixed a memory leak.
Fixed an issue in index search that caused a slowdown when using complex
Planning for queries with multiple
ORoperators in the
WHEREclause has been improved.
pg_pathmanmodule to version 1.5.2. As compared to version 1.4.14 provided in the previous Postgres Pro releases, the following enhancements were introduced:
Added support for multilevel partitioning.
Eliminated update triggers and added
pg_pathman.enable_partitionrouterparameter to enable/disable cross-partition updates.
Provided other miscellaneous bug fixes and improvements. For a full list of changes, see pg_pathman Wiki.
pg_probackupmodule to version 2.0.24. As compared to version 2.0.19 provided in the previous Postgres Pro releases, the following enhancements were introduced:
If unchanged since the previous backup, files that do not store relation data are now skipped in incremental backups.
Version number specified in
pg_probackup.confis now preserved when this file gets updated, which allows to correctly identify pg_probackup version used to take the backup.
Fixed an issue with restoring compressed file blocks and enhanced checks for compression errors. Previously, pg_probackup could not restore file blocks that the
zlibalgorithm failed to compress during backup. This issue could not be detected by the built-in pg_probackup validation mechanism as it occurs on a lower level that validation itself. You are recommended to re-validate existing backups using this pg_probackup version.
Improved validation algorithm. Files are now validated block by block by default, not only in case of file-level checksum mismatch. You can disable this behavior using the
Allowed restarting a backup merge if the previous attempt has been interrupted.
Allowed taking backups from standby servers without connecting to the master. Besides, pg_probackup now uses its built-in mechanism to determine the consistency point, so there is no risk that backups from standby contain any inconsistent data.
Introduced the following changes for Windows version of Postgres Pro:
PL/Perl now requires ActivePerl 5.26.
32-bit Postgres Pro version is no longer provided.
Migration to Version 18.104.22.168
Depending on your current installation, the upgrade procedure will differ.
To upgrade from a Postgres Pro Standard version based on any previous PostgreSQL major release, you can perform a dump/restore using pg_dumpall, or use the pg_upgrade utility. The first option is safer, while the second is faster and can significantly speed up the upgrade process for large databases.
To upgrade from a Postgres Pro Standard version based on the same PostgreSQL major release, a dump/restore is not required.
When upgrading from versions 22.214.171.124 or lower, you must call the
REINDEX command for indexes that used
If you are upgrading from Postgres Pro Standard 126.96.36.199 or lower, you must also use the pgpro_upgrade script provided in this distribution. This script updates metadata information to handle catalog number format change introduced after Postgres Pro Standard 188.8.131.52, as well as rename the
pgpro_build function to
pgpro_source_id. If you are upgrading your Postgres Pro installation from a binary package, the
pgpro_upgrade script is run automatically, unless you are prompted to run it manually.
If you run
pgpro_upgrade manually, you must stop postgres service. The script must be run on behalf of the user owning the database (typically postgres). Running
pgpro_upgrade as root will result in an error. For details, see pgpro_upgrade.
If you have compiled Postgres Pro from source code or created your database in a non-default location, you must run the
pgpro_upgrade script manually.
On RPM-based Linux distributions, if you are upgrading from version 184.108.40.206 or lower, make sure to move the data directory from
pgsql to the
pgpro directory before running the
To migrate from vanilla PostgreSQL 9.6.x, perform a dump/restore using pg_dumpall.
