E.25. Postgres Pro Enterprise 11.6.1
Release date: 2019-12-13
E.25.1. Overview
This release is based on PostgreSQL 11.6 and Postgres Pro Enterprise 11.5.4. All changes inherited from PostgreSQL 11.6 are listed in PostgreSQL 11.6 Release Notes. As compared with Postgres Pro Enterprise 11.5.4, this version also provides the following changes:
Added support for ALT Linux 9.
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.
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.
Enabled bulk page allocation for indexes.
Fixed handling of temporary tables by autonomous transactions.
Fixed handling of NULL distance values when using k-NN search with SP-GiST.
Fixed an issue caused by removing self-joins from plans when using any condition other than
=in the join operation.Fixed incorrect memory allocation by optimizer in a background process.
Reduced memory consumption when using ICU collations.
Reduced planner's memory consumption and sped up
EXPLAIN ANALYZEfor queries with multipleJOINclauses.Improved stability of the pg_query_state module.
Update pgpro_scheduler:
Changing pgpro_scheduler parameters on the fly does not cause server failures anymore.
pgpro_scheduler stability has been improved for several other corner cases.
Updated multimaster:
Added support for temporary tables.
Added support for updating
enumvalues.Fixed an issue that caused WAL bloating.
Fixed handling of node ID sequences when adding or removing cluster nodes.
Fixed connection logic in multimaster to allow a node to return to the cluster if the domain name of this node can be resolved to different IP addresses.
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.25.2. Migration to Version 11.6.1
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.
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.
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.
