If you really want to see on-disk bitmaps in, you might want to study the
patches and the missing vacuum related bits and then think about submitting
an updated version. My take on the future of that patch is the original
developers aren't terribly motivated to finish it, in much part because some
of the testing people have done vs. 8.3 shows it solves an even smaller
number of issues than originally hoped. my .02 anyway.
