E.10. Postgres Pro Standard 10.11.1
Release Date: 2019-12-09
This release is based on PostgreSQL 10.11 and Postgres Pro Standard 10.10.2. All changes inherited from PostgreSQL 10.11 are listed in PostgreSQL 10.11 Release Notes. Other major changes and enhancements are as follows:
Added support for ALT Linux 9.
Added support for Ubuntu 19.10.
Ended support for Ubuntu 18.10.
Modified the implementation of ICU default collations to ensure that the server can be started after the ICU library has been upgraded. For details, see the migration instructions below.
Reduced memory consumption when using ICU collations.
Reduced planner's memory consumption and sped up
EXPLAIN ANALYZEfor queries with multiple
Forbade access to tables that belong to partition hierarchies in which both pg_pathman and standard PostgreSQL inheritance have been used for partitioning. Mixing different partitioning mechanisms in a single table hierarchy is unsupported and should have never been attempted. Previously, you could get duplicated query results from such table hierarchies.
Updated the mamonsu module to version 2.4.1. You can now convert all system and Postgres Pro metrics definitions provided by mamonsu to the format supported by the native Zabbix agent.
Upgraded pgbouncer to version 1.11.0.
Upgraded pg_probackup to version 2.2.5.
E.10.2. Migration to Version 10.11.1
If you are upgrading from a Postgres Pro Standard version based on the same PostgreSQL major release, it is enough to install the new version into your current installation directory.
Starting from Postgres Pro Standard 10.11.1, 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.
Since pg_probackup delivery model changed in Postgres Pro Standard 10.7.1, when upgrading from a lower version on ALT Linux and Debian-based systems, run
apt dist-upgrade (or
apt-get dist-upgrade) to ensure that all new dependencies are handled correctly. On Windows, you have to run a separate pg_probackup installer to complete the upgrade.
When upgrading from version 10.3.2 or lower, you must call the
REINDEX command for indexes that used
mvarchar types. Besides, if you have been using
pg_repack on Debian-based systems, you have to reinstall its package manually when upgrading to this version since its package got renamed to
To migrate from PostgreSQL or a Postgres Pro Standard release based on a previous PostgreSQL major version, see the migration instructions for version 10. If you are opting for a dump/restore, make sure to use the
--add-collprovider option to correctly choose the provider for the default collation of the migrated database.
