I'm hoping, in the plpgsql function, to unfurl the supplied json into a

select * from json_array_elements_text('[[0, 1], [1, 2]]');
value
--------
[0, 1]
[1, 2]
(2 rows)
works fine, but I can't seem to turn those values into actual ints or
anything else for that matter, apart from text via the
json_array_elements_text() function.
Does this example help?
area=> select (a->>0)::int, (a->>1)::int from json_array_elements('[[0, 1], [1, 2]]') as s(a);
int4 | int4
------+------
0 | 1
1 | 2
(2 rows)
