Subject: Trigger calling a function HELP ME!

Hi all,
first of all, let me explain what I'm trying to do.
I have a table with a fairly complicated trigger. In this trigger I
have a specific set of codelines that can be executed in more than 50
places that works on the new.* fields in order to fix/clean them.
In order to improve readability, I created a function that manages this
small set of codelines, but I'm stuck on the following error:
---
ERROR: return type mismatch in function returning tuple at or near
"imp_test_to_out_test"
CONTEXT: compile of PL/pgSQL function "imp_test_trigger" near line 2
---
as a model, I've created this run-down example:
---
CREATE TABLE public.imp_test
(
id int8,
value text
) WITHOUT OIDS;
CREATE OR REPLACE FUNCTION public.imp_test_to_out_test(imp_test)
RETURNS imp_test AS
'begin
return new;
end;'
LANGUAGE 'plpgsql' STABLE;
CREATE OR REPLACE FUNCTION public.imp_test_trigger()
RETURNS trigger AS
'begin
return imp_test_to_out_test(new);
end;'
LANGUAGE 'plpgsql' STABLE;
CREATE TRIGGER imp_test_trigger_001
BEFORE INSERT OR UPDATE
ON public.imp_test
FOR EACH ROW
EXECUTE PROCEDURE public.imp_test_trigger();
---
Whenever I run the following select, I get the a.m. result:
---
insert into imp_test
(id, value)
values(1, 'A');
---
Can somebody help me?
regards,
