E.18. Postgres Pro Standard 10.4.1

Release Date: 2018-05-23

E.18.1. Overview

This release is based on PostgreSQL 10.4 and Postgres Pro Standard 10.3.2. All changes inherited from PostgreSQL 10.4 are listed in PostgreSQL 10.4 Release Notes. Other major changes and enhancements are as follows:

  • Updated the Section F.29 to fix the sorting order for Cyrillic letters Yo and short I. Make sure to run the REINDEX command to rebuild indexes that use mchar or mvarchar types.

  • Added full-text search support for the Nepali language into the Snowball and Hunspell dictionaries. (See snowball_ext and Hunspell Dictionaries Modules.)

  • Updated jsquery module.

  • Updated PTRACK to version 1.6:

    • Now ptrack doesn't track unlogged relations.

  • Updated the pg_probackup utility to version 2.0.17, which includes the following new features:

    • DELTA mode for incremental backups that reads all data files in the data directory and creates an incremental backup for pages that have changed since the previous backup.

    • New options for restore and validate commands:

      • --immediate option ends recovery as soon as a consistent state is reached.

      • --recovery-target-action option specifies the action the server should take when the recovery target is reached.

      • --recovery-target-name specifies a named savepoint up to which to restore the cluster data.

      • --write-recovery-conf writes a minimal recovery.conf in the output directory to facilitate setting up a standby server.

      For details, see pg_probackup.

  • Updated pg_pathman module to version 1.4.11. As compared to version 1.4.9, the following enhancements were introduced:

    • Fixed an issue with duplicate entries in query results for inherited tables. In general, pg_pathman does not support multilevel partitioning.

    • Fixed a spurious table is being partitioned now error raised by partition_table_concurrently().

    • Relaxed check constraint handling.

    • Fixed incorrect usage of memcpy() in start_bgworker().

    • For a full list of changes, see pg_pathman Wiki.

  • Added pgpro-version and pgpro-edition options to pg_config.

  • The recovery.conf file is now reloaded whenever the main server process receives a SIGHUP signal.

  • Performed multiple bug fixes in the shared_ispell module.

  • On Debian-based systems, renamed the pg_repack package from pg-repack-10 to pg-repack-std-10.

  • Log files are now automatically reopened when a SIGHUP signal is received by the logger process.

  • Improved Postgres Pro Standard version for Windows:

    • Fixed an issue with pasting strings that include symbols of different character sets from clipboard to psql on Windows systems.

    • Updated optimization algorithm for default database configuration.

    • You can now turn off configuration optimization when installing Postgres Pro from the command line by setting the needoptimization option in the INI file to 0.

E.18.2. Migration to Version 10.4.1

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.

Important

When upgrading from version 10.3.2 or lower, you must call the REINDEX command for indexes that used mchar or mvarchar types.

Important

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 pg-repack-std-10.

To migrate from PostgreSQL or a Postgres Pro Standard release based on a previous PostgreSQL major version, see the instructions in Postgres Pro Standard 10.1.1 Release Notes. 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.
