What you have written is a stored procedure not a trigger function.
Trigger functions until 7.2 return generally OPAQUE and after 7.2 they
return TRIGGER. See the example of a trigger below for your function
CREATE OR REPLACE FUNCTION customer_bak_proc() RETURNS TRIGGER AS '
BEGIN
IF T
I am a postgres newbie.
I am trying to create a trigger that will put a copy of a record into a
backup table before update or delete. As I understand it, in order to do
this I must have a function created to do this task.
The function I am trying to create is as follows:
CREATE FUNCTION custome
