btw ... in jsonb.h there is this comment:
* Jsonb Keys and string array elements are treated equivalently when* serialized to text index storage.  One day we may
wishto create an opclass* that only indexes values, but for now keys and values are stored in GIN* indexes in a way
thatdoesn't really consider their relationship to each* other.
 

Is this an obsolete speculation about writing jsonb_hash_ops, or is there
still something worth preserving there?  If so, what?
        regards, tom lane
