Kerberos and fe-auth...

I don't think it's any surprise that I'm hot on kerberos (updated docs
will come, one thing at a time), however I'm really really really
supper annoyed with the fact that I can't specify a way for a host to
optionally use krb5 or optionally use password authentication.  If
you've got kerberos compiled in, you're stuck using kerberos.  Anyone
have any suggetions or preferred ways of handling libpq so that the
fe-auth can fail back to password if krb5 fail?  Thanks.  -sc
