This release is based on PostgreSQL 11.14 and Postgres Pro Standard 11.13.1. All improvements inherited from PostgreSQL 11.14 are listed in PostgreSQL 11.14 Release Notes. Other major changes and enhancements are as follows:
Dropped support for the sr_plan extension.
Upgraded mamonsu to version 3.1.0. Notable changes are as follows:
A new option for
bootstrapis added. With this option, if
-dbnameis not explicitly specified, its value will be automatically set to the database name defined in the
[postgres]section of the mamonsu configuration file.
A critical issue is fixed that could arise when the
bootstrapstep was skipped. In this case, although a user can work with mamonsu under superuser permissions, the special
mamonsuschema is not created, but after creating the auxiliary extension pg_buffercache in any other schema, running mamonsu resulted in errors “
ERROR: relation "mamonsu.pg_buffercache" does not exist...”.
Added support for ALT Linux 10.
Changed the minimum supported Windows versions to Windows 10 and Windows Server 2012 R2.
Ended support for Ubuntu 20.10 and added support for Ubuntu 21.10.
Fixed a pg_probackup issue with archiving WAL from a directory outside of the data directory. Previously, multi-threaded and batch optimizations of
archive-pushprevented such archiving; now it is possible to archive WAL from any directory, but if it is outside of the data directory, multi-threaded and batch optimizations are automatically turned off.
Fixed pg_dumpall to avoid using an insecure search path.
Migration to Version 11.14.1
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.
numeric_le are actually leakproof, they were not marked as such in Postgres Pro Standard 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 Standard 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.
Since pg_probackup delivery model changed in Postgres Pro Standard 11.2.1, 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 Postgres Pro versions 11.11.1 or lower, rebuild covering 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 11.11.2 or lower and take PTRACK backups using pg_probackup, retake a full backup after upgrade.
To migrate from PostgreSQL or a Postgres Pro Standard release based on a previous PostgreSQL major version, see the migration instructions for version 11. 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.
