Finally there is a new version of patch (in attachments).
It provides multicolumn index-only scan for GiST indexes.
- Memory leak is fixed.
- little code cleanup
- example of performance test in attachmens
- function OIDs have debugging values (1111*) just to avoid merge conflicts
while testing patch
Wiki page of the project is
