heya,
Using "www-data" as the backend database username in settings.py
doesn't quite work. If you try to run a ./manage.py syncdb, it spits
out:
Traceback (most recent call last):

psycopg2.OperationalError: FATAL: Ident authentication failed for
user "www-data"
I've changed the authentication in my pg_hba.conf from "ident" to
"password", and it now works with "victorhooi" as the backend database
username =). So there's no need to use a PostgreSQL www-data account.
I'm still curious what changed? Perhaps Ubuntu's default pg_hba.conf
file changed from 9.04 to 10.04? AFAIK, there wasn't any such change,
although I don't have a 9.04 system around to verify.
Anyhow, is this the recommended configuration, what I have now? Just
want to know the right way of doing things?
Cheers,
Victor
