ERROR: NEW used in non-rule query (was Parse error a in short stored procedure : What's wrong ?)

> remove a ) at the end, 3 is enough ;-)

You were right, and I found also some misplaced quotes which I replaced by
the quote_literal() function.

I'm now getting another error :

WARNING: Error occurred while executing PL/pgSQL function
update_mview_contacts
WARNING: line 8 at execute statement
ERROR: NEW used in non-rule query

I don't understand why that stored procedure run very well when it's called
by an UPDATE trigger, and it fails when it is called by an INSERT trigger...
:-(

This procedure is called by theses triggers :

CREATE TRIGGER maj_mview_contacts
AFTER INSERT OR DELETE OR UPDATE ON people
FOR EACH ROW
EXECUTE PROCEDURE update_mview_contacts();

CREATE TRIGGER maj_mview_contacts
AFTER INSERT OR DELETE OR UPDATE ON organizations
FOR EACH ROW
EXECUTE PROCEDURE update_mview_contacts();

And my test is that one :

org_db=> INSERT INTO organizations (pk_fk_cnt_id,org_name) VALUES (94093,'My
Dot Org Organization');
WARNING: Error occurred while executing PL/pgSQL function
update_mview_contacts
WARNING: line 8 at execute statement
ERROR: NEW used in non-rule query

Here's the full code of my stored procedure :
---------------------------------------------

CREATE OR REPLACE FUNCTION update_mview_contacts() RETURNS "trigger"
AS '
BEGIN
IF TG_OP = ''INSERT'' THEN
-- Add the new contact into the materialized view

quote_literal(NEW.pk_fk_cnt_id) || '', '' ||

END IF;

RETURN OLD;
ELSE

RAISE EXCEPTION ''Unknown trigger function operation [%]'', TG_OP;
END IF;
END;

Where is my error(s) ? What can I do to avoid that (or theses) error(s) ?

Thanks really much in advance for your help !
