> Currently for certain types of RexNodes (RexOver, RexCorrelVariable) DrillOptiq does
not convert it to the equivalent logical expressions. In that case we simply return a NullExpression
(minor type: Null) and we error out later in execution when we try to allocate a vector with
minor type Null. We should error out early in DrillOptiq that there was a planning issue indicating
the particular RexNode that wasn't handled correctly.
