Currently, the check for exclusion constraints performs a sanity check
that's slightly too strict -- it assumes that a tuple will conflict with
itself. That is not always the case: the operator might be "<>", in
which case it's perfectly valid for the search for conflicts to not find

This patch simply removes that sanity check, and leaves a comment in
