[OPEN-ILS-GENERAL] Minimum required PostgreSQL version to change with Evergreen 2.11

[Galen Charlton]

Hi,

Summary: With the release of Evergreen 2.11 in the fall, the minimum
required version of PostgreSQL will become 9.3. You can upgrade
PostgreSQL at any time between now and when you upgrade to Evergreen
2.11.

Longer version: At the development meeting yesterday, the developers
decided that with the release of Evergreen 2.11 in the fall, the
minimum required version of PostgreSQL will be 9.3.  This decision was
made for the following reasons:

- Community support for PostgreSQL 9.1 will end in September 2016 (and
consequently, Evergreen's support for 9.1 was deprecated upon the
release of Evergreen 2.10.0).
- There are features in newer versions of Pg that would be useful for
Evergreen to take advantage of.
- Well-supported packages of PostgreSQL 9.3 and later are available
for Debian, Ubuntu, and Fedora via the distributions as well as via
apt.postgresql.org and yum.postgresql.org.

Consequently, we recommend that users of Evergreen plan on upgrading
to PostgreSQL 9.3 (or later) by September of 2016 at the latest (or at
the /very/ latest, as part of upgrading to Evergreen 2.11). Existing
supported versions of Evergreen will work on newer PostgreSQL
versions; it is not necessary to plan on doing an Evergreen upgrade
simply to run a new version of PostgreSQL.

One thing to note is that the current stable releases of Evergreen
(2.10.x, 2.9.x, and 2.8.x) are not expected to ever require Pg 9.3;
any new features that depend on Pg 9.3 will make their appearances
only in Evergreen 2.11 or later.

Regards,

Galen
