E.17.2. Migration to Version 9.6.8.2

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.

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 9.6.7.1 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 9.6.4.1, 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.

Important

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.

Note

On RPM-based Linux distributions, if you are upgrading from version 9.6.2.1 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.
