I'm sure it's using that pg_hba.conf, although I don't see anything in the
log file that indicates the file it is actually using. I shut the postmaster
down, modified it, and started the postmaster.

I tried using 'trust' and the clients are able to connect. Could it be a
case-sensitivity problem with the database name (seeing as it's all caps)?

That looks fine ...

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.

Maybe. You didn't show us what other entries are in your pg_hba file.
If the line you showed us failed to match for some reason, what would
it fall through to using?
