It appears that your package manager failed to create the database named $user for you. The reason that

psql -d template1
works for you is that template1 is a database created by postgres itself, and is present on all installations. You are apparently able to log in to template1, so you must have some rights assigned to you by the database. Try this at a shell prompt:

createdb
and then see if you can log in again with

psql -h localhost

 SELECT RIGHT('000'+CAST(field AS VARCHAR(3)),3)
