This release is based on PostgreSQL 10.19 and Postgres Pro Standard 10.18.1. All changes inherited from PostgreSQL 10.19 are listed in PostgreSQL 10.19 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.
Ended support for Ubuntu 20.10.
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 10.19.1
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.
