Release date: 2017-08-31
This release is based on Postgres Pro Standard 9.6.4.1 and PostgreSQL 9.6.5.
Major enhancements over Postgres Pro Standard 9.6.4.1 include:
Updated pg_pathman module to version 1.4.3. (See Section F.35 and Section F.35.1.1.) As compared to version 1.4.2, the following enhancements were introduced:
Disabled dangerous optimizations for UPDATE and DELETE on PostgreSQL 9.5.
Fixed the following type of query: DELETE FROM single_table USING partitioned_table.
Fixed the output of the EXPLAIN INSERT INTO partitioned_table command when verbose mode is activated.
For a full list of changes, see pg_pathman Wiki.
Enhanced the pg_controldata utility
to enable automatic Postgres Pro upgrades
using the pgpro_upgrade script.
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, 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 Standard 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 after
Postgres Pro Standard 9.6.4.1. If you are upgrading your
Postgres Pro 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.
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.
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.
