Hello. Thanks a lot for review.
Patch updated + rebased on master. check-world is passing. Still not sure about comment formatting. Have you seen any style guid about it except "strict ANSI C comment formatting"? Anyway still need to work on comments. Also, non-MVCC snaphots are now supported. Github is updated too. https://github.com/postgres/postgres/compare/master...michail-nikolaev:offset_index_only Still not sure about questions 0, 2, 3, 4, 5, and 6 from initial mail (about explain, explain analyze, documentation and optimiser).
