Review comment:
Could you filter out this unsupported case outside
`replaceTableScanWithPartitionMetadata`(I think this filtering is not related
to normalization)? e.g., in
https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/OptimizeMetadataOnlyQuery.scala#L53-L55
