[DOCS] error in plpgsql-statements.html#PLPGSQL-SELECT-INTO

[Marcos Truchado]

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.
