If your users always connect through TCP/IP then you can set local 
connections to not use passwords but I'm pretty sure there is no way to 
configure this just for the postgres user (I wish you could).

If you need passworded local connections for users then you'll probably 
want to turn on 'ident' mode just long enough to set the password for 
the postgres user (or some other 'super user').  Then you may also want 
to use the PGPASSWORD environment variable or the .pgpass file to avoid 
typing the password repeatedly.
