Remove 'datlastsysoid'.
It hasn't been used for anything for a long time. Up until recently, we still queried it when dumping very old servers, but since commit 30e7c17, there's no longer any code at all that cares about it. Discussion: http://postgr.es/m/CA+Tgmoa14=BRq0WEd0eevjEMn9EkghDB1FZEkBw7+UAb7tF49A@mail.gmail.com
