Release Date: 2020-08-25
This release is based on PostgreSQL 10.14 and Postgres Pro Standard 10.13.1. All changes inherited from PostgreSQL 10.14 are listed in PostgreSQL 10.14 Release Notes. Other major changes and enhancements are as follows:
Upgraded pg_probackup to latest version 2.4.2:
New options and flags can now be used to add flexibility to
Incremental restore and support for multi-timeline incremental chains have been added.
Postgres Pro parameters
primary_conninfocan be used during restore.
archive-getcommands considerably reworked.
Improvements have been achieved in speed and memory consumption.
See pg_probackup documentation for details.
Added the optional
tuneargument to the
pg-setup initdbcommand. This argument allows you to choose one of the predefined customized configurations for your database cluster.
Ended support for ALT Linux 7, while support for ALT Linux SPT 7 is retained for convenience of existing customers.
Ended support for SUSE Linux Enterprise Server 11.
Fixed race conditions in BRIN index that caused errors:
"failed to find parent tuple for heap-only tuple ...".
The error could occur when the
brin_summarize_new_values()function and HOT updates were executed simultaneously in concurrent transactions.
"corrupted BRIN index: inconsistent range map".
The error could occur when BRIN index's desummarization and a bitmap scan were executed simultaneously in concurrent transactions.
Upgraded mamonsu for Linux systems to version 2.5.1. Now it is based on Python 3. Version 2.3.4 is still provided for Windows systems.
E.6.2. Migration to Version 10.14.1
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.
numeric_le are actually leakproof, they were not marked as such in Postgres Pro Standard 10.11.1 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 10.12.1 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
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.
