Hi,
from this thread http://moodle.org/mod/forum/discuss.php?d=186777 I got the impression that I am the first person to test moodle with PostgreSQL 9.1 - what seems to be a little crazy from my experience ;)
So I would like to ask: which database versions are you testing with? Are you testing moodle with the current beta or even "trunk" or "master" versions of databases (if available) or are you using only beta versions for testing - or only the actual stable releases? I was expecting Moodle developers testing at least the current beta versions of databases to be ahead of problems that might arise from upcoming database updates.
Thank you very much for your attention,
Bughunter
