  • Added support for Rosa Enterprise Linux Server 7 and ROSA COBALT 7 (server edition). The previous versions of these operating systems are no longer supported.

  • Updated pg_pathman module to version 1.5.8. As compared to version 1.5.5 provided in the previous Postgres Pro releases, the following enhancements were introduced:

    • Fixed handling of tables with multilevel partitioning. Previously, SELECT FOR SHARE and SELECT FOR UPDATE commands for such tables could return the following error: ERROR: variable not found in subplan target lists.

    • Enhanced pg_pathman stability.

E.4.2. Migration to Version

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

If you are running Postgres Pro Standard version or higher, it is enough to install the version into the same directory. However, if you are upgrading from PostgreSQL 9.5.x or lower versions of Postgres Pro Standard, some catalog changes should be applied, so 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 9.5.4 or lower, perform a dump/restore using pg_dumpall.
