Odd. One possibility is that the postmaster isn't using the pg_hba.conf
file you think it is (did you signal it to reload its configuration, or
else stop and restart it, after editing the file?). Another idea that
comes to mind is some sort of packet filtering at the network or OS
level ... though I'm not sure how packet filtering could cause this
particular error message.
