Is there a type like a growable array, similar Vector at Java language in postgreSQL?

In Oracle, there is a type like a growable array, similar Vector at Java language.

 

In postgreSQL, is there any type like bellow type?

 

---------------------------------------------------------------------------------------------------------------------
CREATE OR REPLACE PROCEDURE test(
   p_size       in  number
  ,p_proccode  out varchar2
  ,p_procmesg  out varchar2
)
IS

 

  v_count                 number default 0;
  v_dayIndex              number default 0;
  v_size                  number default 0;
 
  type tb_NumTable is table of number(2) index by binary_integer;------------>like a growable array
  t_modifiedTimes tb_NumTable;----------------------------------------------->declare a variable using above defined type.
 
  ....

 

BEGIN

 

....

 

  v_size := nvl(p_size, 0);

 

  for v_count in 1..v_size loop

 

     v_dayIndex := v_dayIndex + 1;

 

     t_modifiedTimes[v_dayIndex ] := v_count;

 

   end loop;

 

  ....
 
  p_proccode := 0;
  p_procmesg := 'OK';
     
EXCEPTION
 
  WHEN OTHERS THEN
    p_proccode := SQLCODE;
    p_procmesg := SUBSTR(SQLERRM, 1, 255);

 

end test;
