PostgreSQL tcp connection

Hello,

I have installed PostgreSQL 7.0.3 on my Mandrake 7.2 Linux system and 
have been trying to get it to listen for TCP connectins.

I added the "-i" command to the /etc/init.d/postgresql script, but still 
it does not seem to accept any connections. I can make local 
connections, but need to be able to have the database on one machine and 
my webserver database connection application on another machine.

Is there something that I have not done correctly and could you please 
tell me how to get this working?

Best Regards,
Lonnie Cumberland
