> PlanVisualizer would result in crashes on some queries (i.e., CreateTable) which does not have corresponding PhysicalPlans support in StarSchemaSimpleCostModel::estimateCardinality.
> https://github.com/apache/incubator-quickstep/blob/master/utility/PlanVisualizer.cpp#L193
> https://github.com/apache/incubator-quickstep/blob/master/query_optimizer/cost_model/StarSchemaSimpleCostModel.cpp#L96
> I was wondering if we could "return 0;", instead of crashing, for the rest of unsupported PhyscalPlans.
