Hi! New version of patch is attached. There are following changes. 1) Since proposed tchnique is not always a "fast" build, it was renamed everywhere in the patch to "buffering" build. 2) Parameter "buffering" now has 3 possible values "yes", "no" and "auto". "auto" means automatic switching from regular index build to buffering one. Currently it just switch when index size exceeds maintenance_work_mem. 3) Holding of many buffers pinned is avoided. 4) Rebased with head.
TODO: 1) Take care about ordered datasets in automatic switching. 2) Take care about concurrent backends in automatic switching. ------ With best regards, Alexander Korotkov.
