You misunderstood, what I said was it's "more or less impossible",
that's different from "impossible".
*If* a feature can be added to plpgsql, it sure can be added to
plpgsql2 too, so of course it should be added to both.
I'm just saying it's much less probable you can add new features to
plpgsql than to plpgsql2, as you have to take into account the risk of
breaking compatibility.
