Release date: 2021-12-08
This release is based on PostgreSQL 11.14 and Postgres Pro Enterprise 11.13.1. All changes inherited from PostgreSQL 11.14 are listed in PostgreSQL 11.14 Release Notes. As compared with Postgres Pro Enterprise 11.13.1, this version also provides the following changes:
Fixed pg_dump to handle 64-bit XID statistics correctly, which is important when upgrading Postgres Pro Enterprise using pg_upgrade. Previously, values over 232 in XID statistics were incorrectly transferred, which led to the launch of autovacuum to prevent transaction ID wraparound.
Fixed an issue with an upgrade of Postgres Pro Enterprise 9.6 cluster to the current major version using pg_upgrade. Previously, it incorrectly converted free space maps of tables larger than 4 TB.
Dropped support for the sr_plan extension.
Upgraded mamonsu to version 3.1.0. Notable changes are as follows:
A new option for bootstrap is added. With this option,
if -dbname is 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 bootstrap step was skipped.
In this case, although a user can work with mamonsu under superuser permissions,
the special mamonsu schema 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.
Enforced the size limit of 16TB to non-system tables with non-unique and not covering B-tree indexes to avoid issues with such indexes in extremely large tables.
Fixed a pg_probackup issue with archiving WAL from a
directory outside of the data directory. Previously, multi-threaded and batch optimizations of archive-push
prevented 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.
Deprecated WAITLSN command.
Leveraged sparse file functionality in Windows for CFS,
which optimizes on-disk size of *.cfm files, up to 1MB each.
If you are upgrading from a Postgres Pro Enterprise release based on the same PostgreSQL major version, it is enough to install the new version into your current installation directory.
Migration of a cluster with tables larger than 16Tb to Postgres Pro Enterprise versions 11 or 10 is not supported.
If you have previously migrated to Postgres Pro Enterprise 11.12.1 or lower, you must run the
REINDEX command to rebuild GIN indexes.
While functions numeric_eq,
numeric_ne, numeric_gt,
numeric_ge, numeric_lt,
and numeric_le are actually leakproof, they were not
marked as such in Postgres Pro Enterprise 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 Enterprise 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.
If you are upgrading from Postgres Pro Enterprise versions 11.11.x or lower and take PTRACK backups using pg_probackup, retake a full backup after upgrade.
To migrate from PostgreSQL, as well as Postgres Pro Standard or Postgres Pro Enterprise based on a previous PostgreSQL major version, see the migration instructions for version 11.
