> Some plan transformations (e.g., `RemoveNoopOperators`) implicitly assume the same `ExprId` refers to the unique attribute. But, `RuleExecutor` does not check this integrity between logical plan transformations. So, this ticket targets at adding this check in `isPlanIntegral` of `Analyzer`/`Optimizer`.
