We use SSPI *both* as a protocol (windows talking to windows) and as an
API to go GSSAPI authentication (windows talking to unix, or windows
talking to windows with extra mit krb libraries).
Now, we can have two different defaults both for SSPI, but that's just
going to be too confusing I think. It's better to just keep the default
at "postgres" in that case, and tell people that if they use AD as their
KDC, they need to change it.
SSPI windows to windows will actually work without doing that, because
it will fallback to NTLM authentication if it's wrong. Windows to Unix
