Hi. I have just learned how to create my own triggers on plpgsql 
language, and I think I have discover an error into the doc:

http://www.postgresql.org/docs/current/static/plpgsql-statements.html#PLPGSQL-SELECT-INTO
------------------------------------------------------------------------

DECLARE
     users_rec RECORD;
     full_name varchar;
 BEGIN
     SELECT INTO users_rec * FROM users WHERE user_id=3;
 
     IF users_rec.homepage IS NULL THEN
         -- user entered no homepage, return "http://"
         RETURN ''http://'';
     END IF;
 END;

------------------------------------------------------------------------
full_name declared, but not used.
