Обсуждение: Bitmap index status

Hi,

I don't want to harass you :), but what's the status with the bitmap 
index code? Is there something I can do to help?

Not at all. We will send you the new patch soon. Your comments are most
appreciated.

Thanks,

Hi Heikki,

The streaming is implemented, as are range queries. I need to bring it up
to HEAD and back-patch to bizgres since... it's not diverged fairly
significantly from that code base.

Two outstanding items are handling vacuum and I was considering having a
bitmap selectivity function but I haven't really looked into it.

Once I bring it up to HEAD I'll post.

Thanks,

Gavin

Code promises for this feature have been unreliable in the past.  :-(
