Oracle => PostgreSQL：％ROWTYPE的数组？

Question

Is there any way in PostgreSQL to declare local type "TABLE OF ..%ROWTYPE INDEX BY BINARY_INTEGER" inside a function like in Oracle?

CREATE OR REPLACE FUNCTION FNC
   RETURN NUMBER
AS
   TYPE TYPE_TB IS TABLE OF ADM_APPLICATIONS%ROWTYPE
      INDEX BY BINARY_INTEGER;

   TB_VAR   TYPE_TB;
BEGIN
   return 1;
END;

Answer 1

For every table there is also a corresponding type (with the same name) available.

So you can do the following:

CREATE OR REPLACE FUNCTION fnc()
   RETURNs integer
AS
$$
declare
   tb_var adm_applications[];
begin
   return 1;
end;
$$
language plpgsql;
