Release date: 2018-03-01
This release is based on Postgres Pro Standard 9.6.8.1 and Postgres Pro Enterprise 9.6.7.1. All improvements inherited from Postgres Pro Standard 9.6.8.1 are listed in Postgres Pro Standard 9.6.8.1 Release Notes.
Main changes over Postgres Pro Enterprise 9.6.7.1 include:
Excluded the pg_wait_sampling module from Windows builds to avoid server crashes.
Depending on your current installation, the upgrade procedure will differ.
To upgrade from a Postgres Pro Enterprise version based on any previous PostgreSQL major release, you can perform a dump/restore using pg_dumpall, or use the pg_upgrade utility. The first option is safer, while the second is faster and can significantly speed up the upgrade process for large databases.
To upgrade from a Postgres Pro Enterprise version
based on the same PostgreSQL major release,
a dump/restore is not required. Instead of the pg_upgrade,
you must use the pgpro_upgrade script provided
in this distribution. This script updates metadata information to
handle catalog number format change introduced in
Postgres Pro Enterprise 9.6.4.1, as well as
renames the pgpro_build function to pgpro_source_id. If you are upgrading your
Postgres Pro Enterprise installation from a binary package, the
pgpro_upgrade script is run automatically, or 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) and PGDATA environment variable should be
set to the directory where database resides. Running pgpro_upgrade
as root will result in an error.
On RPM-based Linux distributions, if you are upgrading from
version 9.6.1.2, make sure to move the data directory from
pgsql to the pgproee
directory before running the pgpro_upgrade script.
To migrate from vanilla PostgreSQL 9.6.x or Postgres Pro, perform a dump/restore using pg_dumpall.
