If the host is localhost, then you don't need to supply the hostname in the
url.
Same goes for the port, if missing it defaults to 5432.
As for hostname/ip address, you can use either - it's only when dealing with
applets when this has to be precise.

The host could be just localhost
if this is running only on localhost, right?
Or do I have to specify an IP?
Thanks,
