Re: Bitmap index AM

Bruce,

We have a bitmap index AM in Bizgres (on PG 8.1.3) that is functional and
achieves very worthwhile (10x+) performance and space objectives.

It is a large patch, and introduces the access method along with modifying
the appropriate executor nodes. The latter part was necessary because of
the need to bypass the in-memory bitmap index when an on-disk bitmap is
available.

Because this patch is large, how do you suggest we go through review? Also,
there is some further work that Jie is doing to support efficient
multi-column indexes that will simplify the code, so we're not quite ready
for patch submission.
