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. regards, tom lane
