…after Vertical merges The problem was that just before creating index granularity the blocks_are_granules_size has been set to true in case of vertical merges, and this forces to use adaptive granulas But, we do not need this, since it is written before vertical merges anyway, vertical merges does not calculate index granularity

But, we do not need this, since it is written before vertical merges anyway, vertical merges does not calculate index granularity
