I'm not for adding a bunch of new action-start timestamps without very
clear use-cases for them, because each one we add means more gettimeday()
overhead that might or might not ever be useful.
I agree that it would be surprising for transaction timestamp to be newer
than statement timestamp. So for now at least, I'd be satisfied with
documenting the behavior.
