Revoke access on pg_user

Hi,

By default, all users can find out what other users exist,
by looking at pg_user (which is a view on pg_shadow). For
privacy reasons I would like to disable that.

So I tried this: REVOKE ALL ON pg_user FROM PUBLIC;
which was acknowledged by the word "REVOKE", and there was
no error message. But it doesn't have any effect. All
users can still perform SELECT on pg_user and see everyone.

What am I doing wrong?

Regards
Oliver

PS: I'm using 7.3.4 on FreeBSD 4.8, if that matters.
