Whatever you suggest. We basically create a world-writeable
socket/database when we do initdb. It is similar to a product
installing in a world-writable directory.

I realize you can lock it down later, but it seems people need to lock
it down _before_ doing initdb or somehow keep it locked down until they
set security. Our new SO_PEERCRED/SCM_CREDS gives us a lockdown option
on Linux/BSD platforms, but not on the others.

If we do the socket permissions thing for initdb, when do we start
setting the socket permissions properly?

I realize there is no easy answer. I just wanted people to know this is
a security hole.
