Hi,
Here is a patch by Heikki Linnakangas with changes for amgetmulti index
access method to amgetbitmap, which returns all matching tuples at once.
The patch also introduces support for candidate matches. The original
post is here:
http://archives.postgresql.org/pgsql-patches/2007-03/msg00163.php
I've made minor changes to the patch:
- fixed all rejects when applying it to the current CVS head.
- fixed counting ntids in gistnext if TIDBitmap is not null.
- added missing expected/bitmapops.out
It passes all regression tests on my system.
Regards,
