And neither answers the original problem:
3. How can the sysadmin prevent a malicious local user from hijacking
the sockets if the postmaster isn't running?
Prevention is much more valuable than ex post detection, IMNSHO.
Probably the first answer is not to run postgres on a machine with
untrusted users, but that's not always possible. Maybe we can't find a
simple cross-platform answer, but that doesn't mean we should not look
at platform-specific answers, at least for documentation.
