Subject: A little utility script to perform search and replace on the whole database.
X-Git-Url: http://git.mjollnir.org/gw?a=commitdiff_plain;h=04337d7531e6d048a24d4a9ffe93ff60f3e68e2a;p=moodle.git

A little utility script to perform search and replace on the whole database.
It's not linked from anywhere yet.

I'm not sure if this will work on PostgreSQL ... can someone test that?
