Re: remaining sql/json patches

I have tested a nested case  but  why is the negative number allowed in subscript(NESTED '$.phones[-1]'COLUMNS), it should error out if the number is negative.

‘postgres[170683]=#’SELECT * FROM JSON_TABLE(jsonb '{
‘...>’         "id" : "0.234567897890",
‘...>’         "name" : { "first":"Johnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnn", "last":"Doe" },
‘...>’         "phones" : [{"type":"home", "number":"555-3762"},
‘...>’                     {"type":"work", "number":"555-7252", "test":123}]}',
‘...>’                '$'
‘...>’                COLUMNS(
‘...>’                     id numeric(2,2) PATH 'lax $.id',
‘...>’                     last_name varCHAR(10) PATH 'lax $.name.last', first_name VARCHAR(10) PATH 'lax $.name.first',
‘...>’                      NESTED '$.phones[-1]'COLUMNS (
‘...>’                    "type" VARCHAR(10),
‘...>’                    "number" VARCHAR(10)
‘...>’ )
‘...>’      )
‘...>’   ) as t;
  id  | last_name | first_name | type | number
------+-----------+------------+------+--------
 0.23 | Doe       | Johnnnnnnn |      |
(1 row)
