Hi all, I've updated the bitmap index patch. It can be found here:
http://www.alcove.com.au/~swm/bitmap-2007-03-12.diff This fixes some bugs introduced in the last patch, catches up to HEAD and tidies up the executor code. I want to do a little more tidying, such as reverting the name changes we made. multiscan still sounds alright. I've been thinking about vacuum as well. Something along the lines of what Heikki mentioned earlier -- namely, the ability to iterate the bitmap setbit by setbit is in order. What I have in mind, though, is that when we find a reaped setbit, we mark the position and continue to iterate until we find a non reaped setbit. When, we update the underlying bitmap vector to reflect the non-set bits. Thoughts?
