  • The pg_variables module now supports transactional variables. (See Section F.37.)

  • The auto_explain can now display planning time.

  • Postgres Pro Standard version for Windows has been improved:

E.8.2. Migration to Version

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

If you are running Postgres Pro, it is enough to install the version into the same directory. For earlier Postgres Pro versions, pgpro_upgrade script is required to complete the upgrade:

  • If you are upgrading your installation from a binary package, and your database is in the default location, pgpro_upgrade is run automatically, unless you are prompted to run it manually.

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


Before launching pgpro_upgrade manually, you must stop the 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.

To migrate to this version from vanilla PostgreSQL, perform a dump/restore using pg_dumpall.
