Subject: Bug #6147 - Upgrade from 1.5.x breaks with Postgres 7.4.x
X-Git-Url: http://git.mjollnir.org/gw?a=commitdiff_plain;h=889e6b46f48e0d63bf016befdc08cedf6bd97b20;p=moodle.git

Bug #6147 - Upgrade from 1.5.x breaks with Postgres 7.4.x

Even though Postgres 7.4.x is officially supported, several upgrade scripts use syntax that only works in Postgres 8.x. and it's impossible to finish the upgrade.

The attached patch fixes those scripts.

Saludos. I�aki.
