<p> This allows vacuum to target specific pages for possible free space
without requiring a sequential scan.

</li><li>Auto-fill the free space map by scanning the buffer cache or by
checking pages written by the background writer
</li><li>Create a bitmap of pages that need vacuuming
<p> 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.
