Pushed. Rebased patchset is attached. I propose to limit consideration during this commitfest to this set of 7 remaining patches. The rest of patches could be considered later. I made some minor editing in preparation to commit. But I decided I've couple more notes to Nikita. * 0003 extracts part of fields from BTScanOpaqueData struct into new BTScanStateData struct. However, there is a big comment regarding BTScanOpaqueData just before definition of BTScanPosItem. It needs to be revised. * 0004 adds "knnState" field to BTScanOpaqueData in addition to "state" field. Wherein "knnState" might unused during knn scan if it could be done in one direction. This seems counter-intuitive. Could we rework this to have "forwardState" and "backwardState" fields instead of "state" and "knnState"? ------ Alexander Korotkov Postgres Professional: http://www.postgrespro.com The Russian Postgres Company
