First off, are the users logging into the same machine that the database
server is running on? If so, than you don't need to run an ident server,
you can use domain sockets for connections and the getpeeruid function
will be used to do ident authentication.

You can use iptables to do this. Block tcp traffic to the identd port
that isn't coming from loopback (though this implies that you have the
situation above and shouldn't be using identd) or if the postgres
server is on another machine, restrict traffic based on IP address.
