I'm not sure what your intent here is, but if the idea is that a json array
would magically cast to a bool or a number data type I think that's a bad idea.
My idea, of course, is not about casting any json array to a scalar. It is only
about helper subroutine for extraction of top-level jsonb scalars that are
always
stored as one-element pseudo-arrays with special flag F_SCALAR in the array
header.
