Vitaliy Zakaznikov ea83a4cafa * Removing 'hash' column from WATCH [db.live_view] EVENTS query result
as hash of the result are not usually provided in ClickHouse.
  This is also done to match the implementation of the SELECT query that only
  returns '_version' virtual column when using LIVE VIEW tables.
