two ways.

1: Set the pg server to just trust this user, connecting to x database
or all databases using the pg_hba.conf file
2: Set the normal md5 method in pg_hba.conf and use .pgpass file
(http://wiki.postgresql.org/wiki/Pgpass) to set a password for libpq
to use when that user logs into the db.

 You have two options:

 1) insert a line in ~/.pgpass file in your home directory for that
 database user
 (http://www.postgresql.org/docs/9.0/static/libpq-pgpass.html)
 2) insert a 'trust' rule for that user in the pg_hba.conf for local
 connections
 (http://www.postgresql.org/docs/9.0/static/auth-pg-hba-conf.html)

 I would personally go with #1 in production environment.

 Cheers,
 Gabriele
