Like the is operator, the is not operator compares the memory location of the two objects. In this case we get our result as False because the problem with sorted() method is it only works on the top-level of a dictionary i.e., onto the keys and not on their values as can be verified by above code. json_object ( keys text [], values text [] ) json jsonb_object ( keys text [], values text [] ) jsonb This form of json_object takes keys and values pairwise from separate text arrays.
