[Dongsoo Yoon]

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;
