@Peter, Bob: Thanks. I had a wrong notion of "listen_addresses"!
Everything works fine now...

One final question: Is there any "security" related difference
between, listen_addresses='localhost, 1.2.3.4' and
listen_addresses='*' that I should be aware of? There is only one
network card on the server machine, so does it matter?
