Well, something is quite wrong then.  Find your postgresql.conf file and
see what port it is set to there.  port 1042 is definitely not the
default port.

Also, try two things:

nmap -p 1042
psql -h 127.0.0.1 -p 1042

If nmap can see the port open, and psql can open it, then you can just
use it like that by specifying that port each time in your connect
string.

IF the database is configured for port 1042, then it might not be a
firewall, just a misconfiguration of the database.
