\COPY customer(name, location, status , c_type , bill_attention , bill_addresse , bill_address_1 , bill_address_2 , bill_city , bill_state , bill_country , ship_attention , ship_addresse , ship_address_1 , ship_address_2, ship_city ,ship_state ) from '/home/stan/pm_db/live_data/ready/customer.csv' DELIMITER ',' CSV HEADER ;

and here is the function

CREATE FUNCTION fix_customer_types_case()
RETURNS trigger AS $$
BEGIN
if NEW.c_type IS NOT NULL
THEN
NEW.c_type := upper(cast( NEW.c_type AS TEXT));
END IF ;
if NEW.status IS NOT NULL
THEN
RAISE NOTICE 'Called With %', NEW.status;
NEW.status := upper(cast( NEW.status AS TEXT));
END IF ;
RAISE NOTICE 'Left With With %', NEW.status;
RAISE NOTICE 'Left With With %', NEW.c_type;
return NEW;
END;
$$
LANGUAGE PLPGSQL;

if I do an insert this function is called. However it IS NOT called for the
above copy command. How can I fix that?

This line from the page you referenced implies this should work, but i must be
doing something wrong:

COPY FROM will invoke any triggers and check constraints on the destination
table. However, it will not invoke rules.
