Postgre SQL TCP/IP access FC2?

[Eric Scott]

Yo;  I'm trying to learn database access in C# on my FC2 box, but when I 
compile my code it get's "connection refused" from my postgresql 
installation (Set up with Webmin).  I googled and found that peeps tend 
to have this problem with the Npgsql C# class because Npqsql can't 
access PostGreSQL through Unix sockets, only TCP/IP.

Anyway, how do I enable TCP/IP connection in PostGreSQL?  All the 
howto's I found didn't seem to apply to my Fedora 2 system, as 
/etc/postgresql.conf doesn't exist (Yes, PostGreSQL IS installed and 
activated, or at least Webmin thinks so.)
           Thanx,
