    Description

      SimpleFetchOptimizer optimizes "select * from session_orc limit 1;"

      But when an alias view is created like "create view session as select * from session_orc";

      The simple fetch optimizer fails to kick in and optimize away "select * from session limit 1;" as a fetch only task.
