Hi Aaron,

No idea why Red Hat are so far behind. Officially, Postgres was end-of-
life in July 2014 (http://www.postgresql.org/support/versioning/), which
is way past use-by date.

It may not be much immediate use at your end but, when talking to people
who say they're effectively version-locked because of the SOE, there is
an official alternative. If you're doing the full Red Hat Enterprise
thing, which many unis are because the academic pricing is nice, you
should have access to "Red Hat Software Collections" (I think it's
enabled by default for academic licensing), which adds Postgres 9.2. So
they actually can be supported *and* current. (I discovered this by
accident here, and had just installed these packages when I saw your
response with the patch, so I immediately backed out to avoid even more
upgrading.)

Anyway, thanks for the quick fix, made my life much easier.

Cheers,
Marcus

Bug description:
  Upgrading from 1.5.1 to versions higher than 1.9 (either directly or incrementally by version) fails on Postgres 8.4.
  (And I'm assuming any version of Postgres prior to 9.1.)

  Existing installation of Mahara 1.5.1.
  Run through normal upgrade steps.
  Expected result: Successful upgrade.
  Actual result: upgrade screen reports this error in core upgrade section:

  Could not execute command: UPDATE "artefact" SET path = CONCAT('/', id) WHERE id IN (SELECT id FROM "artefact" WHERE path IS NULL AND parent IS NULL LIMIT 200)

  (Why does it say "postgres7 error" above?)

  It looks like it's asking Postgres to use the CONCAT function which, as far as I'm aware, did not exist in Postgres until 9.1. 
  http://www.postgresql.org/docs/8.4/static/functions-string.html
  http://www.postgresql.org/docs/9.1/static/functions-string.html

  Mahara explicitly states that it's supported on "PostgreSQL, all
  versions from 8.3" (

  )
