Yeah, that's more or less what I was thinking. The argument for
changing current_timestamp seems to be really just spec compliance;
that doesn't apply to now() or timeofday().

I'd be inclined to just do it; we have not been very good about
following through on multi-version sequences of changes. And the
folks who want a standard-compliant current_timestamp aren't going
to want to migrate to now('statement') instead ...
