I spent some thought on that.
You'd need to wait until the user is authenticated before you can determine
if he/she is a superuser and may connect (otherwise I think it would be a
security leak that enables any attacker to find out whether a given user is
a superuser without knowing the password).

By that time the server process is already forked.
I couldn't see a way to check the postmaster state at that point,
so I decided not to try and keep it simple.

If you have any ideas how I could do such a check reasonably,
I'd be happy to try it, because basically I think it would be the
right thing.
