Hey hackers,

I am sorry, but is it possible to implement BTW ability to
check exactly status of authentication from libpq ? As for now,
the only way to check failed authentication is parsing the error
message, that is sadly.

OK, that is easy to fix.  The only downside is that if you misconfigured
.pgpass (which is what I used for testing), you have to wait 60 seconds
to get the "cannot connect" error message.  Is that OK?
