> There are some tests in 
> query_test.test_runtime_filters.TestRuntimeRowFilters.test_row_filters
> that are failing which have a union in them.
> The code can be traced to the fact that ColumnStats are added to union slot descriptors in the SetOperationStmt code.  This code needs to be applied to the Calcite code.
