> * Create a bitmap of pages that need vacuuming
>
>   Instead of sequentially scanning the entire table, have the background
>   writer or some other process record pages that have expired rows, then
>   VACUUM can look at just those pages rather than the entire table.  In
>   the event of a system crash, the bitmap would probably be invalidated.
