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
Using /etc/hosts on:  spe191

Trying DNS
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
psql: could not connect to server: Connection refused
        Is the server running on host "spe176.testdrive.hp.com" and accepting

$ psql -l -p 5440 -h spe17dddfqz
