I seem to recall that, at one point, we actually we doing this
automatically in libpq- that is, grabbing the Kerberos princ and then
using it to auth. That was too constrained though, as we wanted to be
able to have users with names other than their princs, but perhaps we
should have just made it optional instead, perhaps using an environment
variable. Would that work for you and the general users? I'm on the
fence about making that the default again since it's possible we would
break things for existing users...
Thanks,
