-----------------------------------------

             Summary: Generalize p(x) IS TRUE/FALSE/UNKNOWN handling in RexSimplify
                 Key: CALCITE-2326
                 URL: https://issues.apache.org/jira/browse/CALCITE-2326
             Project: Calcite
          Issue Type: Improvement
            Reporter: Zoltan Haindrich
            Assignee: Zoltan Haindrich


Currently only IS TRUE is handle by the unknownAsFalse field variable.

The main goal would be to extend the logic to also handle IS FALSE cases (and possibly IS UNKNOWN too)
