Thank you for the suggestion, this sounds appealing. But I have two questions:

* why it should be a jsonb array, not a regular array?

* it would introduce the idea of jsonb element type expressed in text format,
so "string", "numeric", "boolean" etc - are there any consequences of that?
As far as I understand so far there was only jsonb_typeof.

Oh, sorry, stupid copy-paste mistake in the condition. Just for the records,
I've attached fixed version of the previous patch (without any changes about an
array instead of a boolean flag).
