Re: Connection refused. Check that the hostname and port are correct

That appears to be the JDBC driver is not able to connect to the PostgreSQL
database.

Try out the following:

- See if there is any firewall running, run 'iptables -F" on the database
server machine to disable it for a while and then test the same Java code
- Check the routing tables info and see if there is anything missing there.
- If the above two are okay and still its not connecting try out settng the
following in your pg_hba.conf file:

host all all 127.0.0.1/32 trust
host all all 0.0.0.0/0 trust

and then do a 'pg_ctl reload' and see if that now lets you connect through
the JDBC driver or not locally and over the lan.

Thanks,
