Okay, that probably means there's something wacko about my Kerberos
setup.  It's quite likely got something to do with the fact that I
set up the KDC on the same machine where I'm doing the PG testing,
which is surely a case that would never be sane in practice.

[ thinks for a bit... ]  In this context there's some ambiguity as to
whether 'rh2' should resolve as 127.0.0.1 or the machine's real IP
address, and no doubt something is making the wrong choice someplace.
That's probably how the localdomain lookups got into it.
