You're right that the only suitable core function is going to be
json[b]_to_recordset, but I don't see why you can't extend the
existing example for that.  Something like

# select * from rows from (json_to_recordset('[{"a":1,"b":"foo"},{"a":"2","c":"bar"}]') as (x int, y text), generate_series(1,3)) as x(a,b,s) ;
 a |  b  | s 
---+-----+---
 1 | foo | 1
 2 |     | 2
   |     | 3
(3 rows)

would illustrate all the principles.
