I haven't read the code, but my guess is that psql does the following:

a) Grabs the user and database name from command line.
b) Looks up dbname in pgpassfile to get host and port number etc.
c) Connects to host:port and uses supplied username/password.

When the connect fails in step c), the error should be "connection failed".

Is this not how it should work?
