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.
