  // History-table will be generyted in V1.3 - SQL without that column, while base table still contains that column
  // When creating the "with_history" view, the DB complains, because the tables do not match.
  // In V1.4 the column will be dropped in base table AND history table.
  // This could be probably fixed, by generating history table also with dropped columns
