Trigger calling a function HELP ME! (2)

Sorry. I realize I slipped an error in my code:

the code is:
---
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 $1;
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();
---

This is your problem. NEW is a special variable, and I don't think you can
pass it into another function (other than as NEW.col1, NEW.col2, NEW.col3
etc).

You can however use TG_NAME or TG_RELNAME to see what trigger/table called
you. I find that's helpful.

So, If I have to do a record-wide manipulation (almost all the fields)
to the NEW record just before returning from the trigger, what other
possibility do you suggest?

thanks for your kind answer...

One other issue, as I understand it, NEW (and OLD) is a variable of
type record, so you should be able to pass it to a function and get it
as a return value, but it seems that there is a bug reported for
version 7.2.1 that inhibits the use of record as type to be passed to a
function.

any suggestion?
