Обсуждение: [Fwd: bug ? get_groname: group 0 not found]

I posted this message in pgsql-novice, but got no answer.
I dare forward it to pgsql-hackers, though I fear it could be a misuse
of that list.

Could you post an answer on novice since I've not subscribed to hackers.
(Too high level for me, I think)

Please look at my answer for Wim Aarts question "can grolist in pg_group be
updated" in the GENERAL list. There you can found an URL for an administration
tool which handles the group access for you.
