Are these the set that means UPDATE/DELETE can now do partition pruning?
I think that's a significant improvement, because table partitioning
becomes usable in situations where it previously wasn't, so let's
mention it.

There's an entry that says we allow subscripting of jsonb, but the

and jsonb is just the first implementation. I think this should be
mentioned.

This is one small step towards compliance, I think, so it should be
mentioned.
