Any particular reason this can't be a normal table in pg_catalog which
you can select/update.

I've been trying to convince people for a while now that the
appropriate tz string for australia is AEST/ACST/AWST but no-one seems
convinced yet. Hence, I never actually specify timezones and all my
timestamps are inserted as GMT.

IMHO, you should simply setup the table so that it is backward
compatable and let people edit it themselves. You're never going to be
able to convince anyone that people arn't relying on it exactly the way
it is now. The most important thing is to get rid of the
"australian_timezones" hack, everything else is bonus.

Good question...

Have a nice day,
