Having thought about this some more,
the function name should of course be jsonb_unnest(),
similar to how unnest() works for normal arrays:
SELECT unnest(array[[3,2],[1,4]]);
unnest
--------
3
2
1
4
(4 rows)
SELECT jsonb_unnest('[[3,2],[1,4]]'::jsonb);
jsonb_unnest
--------------------
3
2
1
4
(4 rows)
Thoughts?
