plpgsql out parameter with select into - Mailing list pgsql-sql

Hi!

My question is, how can I get the out parameter from a function with
SELECT INTO by name?
I mean:

create function testfunc1(OUT _status integer) returns integer as
$BODY$       _status := 0;
$BODY$
language plpgsql;

create function testfunc2() as
declare       status integer;
$BODY$       select into status * from testfunc1();
$BODY$
language plpgsql;

create function testfunc3() as
declare       status integer;
$BODY$       select into status _status from testfunc1();
$BODY$
language plpgsql;

testfunc2 works, testfunc3 not.

Thanks in advance:
