trait NormalizeableRelation extends AnyRef
NormalizeableRelation is extended by relations that contain non-deterministic or time-dependent objects that need to be normalized in the NormalizePlan. This way logical plans produced by different calls to the Analyzer could be compared.
This is used in unit tests and to check whether the plans from the fixed-point and the single-pass Analyzers are the same.
