pg_hba.conf configuration

Hi,
    Presumably to make a connection to a remote database, I need to start
the postmaster with the -i switch, and configure the pg_hba.conf file? Can
you tell me what needs to be edited in this file please? A single connection
will suffice, ie appserver host to the DB host. Do I add my IP anywhere in
this file? (the file being edited obviously being situated at the DB host!)

Thanks very much

Paul.
