I think we should try to create the full path if necessary, and simply
throw an error if we can't.

 And, I think - we should switch back to default pgpass configuration file.

Remember, it's environment variable. User can specify anything in there. Some garbage value as well. If we don't do any validation there, user will automatically see error with complain about file ?

Existing code creates directory postgresql (only on windows) according to http://www.postgresql.org/docs/9.3/static/libpq-pgpass.html[http://www.postgresql.org/docs/9.3/static/libpq-pgpass.html] , and it doesn't create file. I'm not sure whether this kind of validation is expected in this function.
