Fixed a bug causing crashes on RESET ALL.
Fixed WHERE conditions that point to gaps between partitions.
Restored compatibility with pg_repack.
For the full list of changes, see pg_pathman Wiki.
Updated the pg_probackup utility from version 2.0.2 to 2.0.11, which includes the following new features:
Password prompt interruption is now handled correctly.
The provided passwords are checked to be is non-empty.
The files that have not changed since the previous backup are not included into the next incremental backup.
Database version is now added into backup meta information.
Other miscellaneous bug fixes.
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 9.6.5.1, it is enough to install the new
version into your current installation directory.
When upgrading from Postgres Pro Standard 9.6.4.1 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. 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.
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.
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.
