> If the RelSubset has no best RelNode, we iterate through all of the RelNodes
> until we find one that has appropriate Metadata. But if the RelNode we choose
> has already been visited, the CyclicMetadataException is thrown, but not
> caught. We should catch the exception and try again on another RelNode.
