it's kind of long (really just a lot of compares of old/new values.
The relevant portion (that selects from user_profile) looks like this:
BEGIN
SELECT user_id, user_ip INTO my_user_id, my_user_ip FROM
audit_metadata WHERE pg_pid = getpid();
IF ((NOT FOUND) OR (my_user_id = -1)) THEN
SELECT user_id INTO my_user_id FROM user_profile WHERE username
= 'db-'||CURRENT_USER and user_type='DBASE';
IF (NOT FOUND) THEN
RAISE EXCEPTION 'USERNAME NOT FOUND IN USER_PROFILE: %
',CURRENT_USER;
END IF;
my_user_ip := inet_client_addr();
END IF;
INSERT INTO audit .....
END;
