ok

I think we'd possibly be better off with simply returning a flat array, [key1, value1, ...]

Thats's what the hstore(text[]) and json_object(text[]) functions accept, along with the 2D variant, if we want a precedent.

It can be one of supported variant. I should not be one, because we cannot to simply iterate over it

Next possibility is teach FOREACH to take key and value in one step.
