E.16.1. Overview

This release is based on PostgreSQL 9.6.9 and Postgres Pro Standard All improvements inherited from PostgreSQL 9.6.9 are listed in PostgreSQL 9.6.9 Release Notes.

Major enhancements over Postgres Pro Standard include:

  • 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.

  • 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 PTRACK to version 1.6:

    • Now ptrack doesn't track unlogged relations.

  • Updated jsquery module.

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

E.16.2. Migration to Version

Depending on your current installation, the upgrade procedure will differ.

To upgrade from a Postgres Pro Standard version based on any previous PostgreSQL major release, make sure you have installed its latest minor version, and then perform a dump/restore using pg_dumpall or use the pg_upgrade utility.


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

To upgrade from a Postgres Pro Standard version based on the same PostgreSQL major release, a dump/restore is not required. If you are upgrading from Postgres Pro Standard or lower, you must also use the pgpro_upgrade script provided in this distribution. This script updates metadata information to handle catalog number format change introduced after Postgres Pro Standard, as well as rename the pgpro_build function to pgpro_source_id. If you are upgrading your Postgres Pro installation from a binary package, the pgpro_upgrade script is run automatically, unless you are prompted to run it manually.


If you run pgpro_upgrade manually, you must stop postgres service. The script must be run on behalf of the user owning the database (typically postgres). Running pgpro_upgrade as root will result in an error. For details, see pgpro_upgrade.

If you have compiled Postgres Pro from source code or created your database in a non-default location, you must run the pgpro_upgrade script manually.


On RPM-based Linux distributions, if you are upgrading from version or lower, make sure to move the data directory from pgsql to the pgpro directory before running the pgpro_upgrade script.

To migrate from vanilla PostgreSQL 9.6.x, perform a dump/restore using pg_dumpall.
