[GENERAL] array_to_records function

[Yudie Pg]

Here I'm posting a function to convert array to records.
any other suggestions are welcome

create or replace function array_to_records(int[]) RETURNS SETOF record AS
$$
DECLARE
  ret_rec record;
  a int;
  b int;
BEGIN
   b = length(array_dims($1));
   a = substr(array_dims($1),4, (b-4)  );
   FOR i IN 1.. a LOOP
     FOR ret_rec IN select i, $1[i] LOOP
     RETURN NEXT ret_rec;
     END LOOP;
   END LOOP;
   RETURN;
END;
$$
LANGUAGE 'plpgsql';
