Log message:
    Divide functions into three volatility classes (immutable, stable, and
    volatile), rather than the old cachable/noncachable distinction.  This
    allows indexscan optimizations in many places where we formerly didn't.
    Also, add a pronamespace column to pg_proc (it doesn't do anything yet,
    however).
