E.26. Postgres Pro Standard

Release date: 2017-02-22

E.26.1. Overview

This release is based on Postgres Pro Standard and PostgreSQL 9.6.2.

Major enhancements over Postgres Pro Standard include:

  • Module pg_pathman has been updated to version 1.3 (see Section F.36.1.1).

  • The sr_plan module is now initialized independently for each database instance.

  • Syntax for covering indexes has been changed. Now the keyword INCLUDING is replaced by INCLUDE. The previous syntax still works, but is deprecated (see Section 11.6).

  • RHEL-based distributions are installed in a separate location, so the Postgres Pro database can be installed in parallel with an existing PostgreSQL database.

  • Improved the algorithm of automatic TCP-port selection for the case of parallel installation of different versions of the product on Windows systems.

  • Updated the pg_probackup backup manager:

    • Added retention show and retention purge commands to implement retention policy.

    • Added support for incremental backup of compressed page files. Compressed files are the feature of the Postgres Pro Enterprise.

    • Fixed validate command. The backup_id parameter is optional now.

E.26.2. Migration to Version

A dump/restore using pg_dumpall, or use of pg_upgrade, is required for those wishing to migrate data from any previous major release.

A dump/restore is not required for those running

However, if you are upgrading from vanilla PostgreSQL 9.6.x, some catalog changes should be applied.

If you use binary packages, and your database is in the default location, this upgrade should be performed automatically. If you've compiled Postgres Pro from source or create your database in a non-default location, running initdb manually, you should run pgpro_upgrade script provided in this distribution.

Before running the script, you should stop postgres service. Script should be run on behalf of the user owning the database (typically postgres) and PGDATA environment variable should be set to the directory where database resides.
