The docs seem to have bug:
it says that the return value is SETOF json
(http://www.postgresql.org/docs/devel/static/functions-json.html)
While in reality (and based on name) it's setof text:
(depesz(at)[local]:5930) 14:45:43 [depesz]
$ \df json_array_elements_text
List of functions
Schema | Name | Result data type | Argument data types | Type
------------+--------------------------+------------------+--------------------------------+--------
pg_catalog | json_array_elements_text | SETOF text | from_json json, OUT value text | normal
(1 row)
Best regards,
