Thanks @rednaxelafx for the fix and pinging me. I think you are right that `EquivalentExpressions.addExpr()` should be guarded by `supportedExpression()` if we guard `getExprState()`. But, I'm not sure it is right that we don't deduplicate the `max(transform(array(id), x -> x))` in your example query. Probably the real issue here is that in`PhysicalAggregation` the class `EquivalentExpressions` is used for simply deduplicating whole expressions while on executors we use it for common subexpression elimination. In the former case we don't need the `LambdaVariable ` guard but in the latter one we need it. So maybe we should add a argument to `EquivalentExpressions` to enable/disable the guards and in `PhysicalAggregation` we should disable it? -- This is an automated message from the Apache Git Service.
