PostgreSQL problem - Connection refused.

Hello

I tried to connect to PostgreSQL from my simple java code (on the same server), but received following error:

[code:1]Connection refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections.[/code:1]

What should I do to succesfully connect to the database? PostgreSQL has been installed via Webmin and works properly (I can add tables etc. using virtualmin).

Few details: Same error message for local and remote calls. When I type: netstat -ln --tcp I don't see any open 5432 port. Does postgres installed by webmin run on another port? I have a latest stack of virtualmin/webmin/usermin installed automatically on Debian 40 etch minimal. Besides I know this is not a local/remote access problem I set this special "any network host" in webmin/servers/PostgreSQL Database Server/Allowed Hosts but there is no difference - error still exists.

Thanks in advance for help!
