Couldn't duplicate this using HP's testdrive systems (HP 11.11).
I do get a message of exactly that spelling when providing a
deliberately incorrect hostname, though. I suspect pilot error on
your part, or misconfiguration of your DNS setup.
$ uname -a
HP-UX spe191 B.11.11 U 9000/800 1865940626 unlimited-user license
-- spe176 is a nearby machine that's not in /etc/hosts:
$ nslookup spe176

Name: spe176.testdrive.hp.com
Address: 192.233.54.176
$ psql -l -p 5440 -h spe176
psql: could not connect to server: Connection refused
Is the server running on host "spe176" and accepting
TCP/IP connections on port 5440?
$ psql -l -p 5440 -h spe176.testdrive.hp.com
