I took a quick look at the code, and from what I can tell this is
because PQconnectionNeedsPassword() always returns false if a
pgpass.conf has been used. There is no handling the case where pgpass
is used, but has an incorrect password.

Does anybody recall the specific reason for this? Do we need a way for
pg_ctl to figure this out, or do we need to change it in
PQconnecitonNeedsPassword()?
