      Fixed bug #19579: at range analysis optimizer did not take into · c467be8d

      account predicates that become sargable after reading const tables.
      In some cases this resulted in choosing non-optimal execution plans.
      Now info of such potentially saragable predicates is saved in
      an array and after reading const tables we check whether this
      predicates has become saragable.
