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.
* Auto-fill the free space map by scanning the buffer cache or by
checking pages written by the background writer
* Auto-vacuum
o Move into the backend code
o Scan the buffer cache to find free space or use background writer
o Use free-space map information to guide refilling
o Do VACUUM FULL if table is nearly empty?
