Обсуждение: pgsql: Update nbtree README's "Scans during Recovery".

Update nbtree README's "Scans during Recovery".

get_actual_variable_range() hasn't used a dirty snapshot since commit
3ca930fc3, which invented a new snapshot type specifically to meet
selfuncs.c's requirements (HeapTupleSatisfiesNonVacuumable() type
snapshots were added).
