This is pretty bizarre ... offhand I would not have thought that the
postmaster depended on DNS service at all. Were you maybe using DNS
names instead of IP addresses in pg_hba.conf? What exactly does
"would not accept" mean --- what was the exact error message,
and was there anything in the postmaster log?
