So now we don't have anything that mentions ALTER TYPE / SUBSCRIPT,
because the item is about JSONB, not about subscripts.  Moreover it
seems misplaced in the "functions" subsection -- subscripting is
replacing what used to be function calls, but really it's more than
that.  I think it should be in "datatypes", and I further think it
should mention ALTER TYPE SUBSCRIPT too.

I, um, again think that the item should not be primarily about JSONB,
but about our (IMO groundbreaking) extensible subscripting work.
