--------------------------------------------------------

After applying this fix to 3.3.2, I still see some slowness here with a very 
tall query tree: 
https://gist.github.com/MasterDDT/422f933d91f59becf3924f01d03d5456 (search for 
DeduplicateRelations)

Is it safe to skip this analyzer rule? Or another way to speed it up? cc
