I think you could effectively disable the pgpass file (for a given
application) if the application always requires an explicit, non-blank
password from the user.
libpq won't use .pgpass if the connection string passed to PQconnectdb()
(or whatever connection function you happen to be using) includes a
"password=foo" clause, right?
