Instaltiating an ARRAY within a function

===========================================

CREATE OR REPLACE FUNCTION arr( inout x varchar[] )
AS
$Z$
DECLARE
i integer;
BEGIN
select ARRAY['Danny','Eissam','Moshe'] into x;
end;
$Z$ LANGUAGE 'plpgsql' VOLATILE;

===========================================

CREATE OR REPLACE FUNCTION callarr()
returns integer
AS
$Z$
DECLARE
x varchar[6];
BEGIN
perform arr(x);
RAISE NOTICE 'x[1]=%',x[1];
return 0;
end;
$Z$ LANGUAGE 'plpgsql' VOLATILE;

===========================================

select callarr();
NOTICE: x[1]=<NULL> ??? Should have been DANNY

Should it work?

Thanks

Danny
