Mark,
As Joshua said, you can modify pg_hba.conf. What's happening is
PostgreSQL is configured to require a password for the IP address that
user is connecting from, but you're not supplying one. Set that user
and the IP address they connect from to "trust" security in pg_hba.conf
and bounce PostgreSQL.
An alternative approach is to add the required password to your user's
.pgpass file however I've never used those so cannot comment.
