Review Comment:
   I agree with you that it's not a good idea to store the storage table in 
another catalog than the materialized view. My initial proposal didn't include 
the catalog. This would also get us around the issues with the "catalog alias" 
problem.
   
   But I think some comments wanted to include the catalog. (I can't find it 
though)
   
   I think having a dedicated namespace for all storage tables might be a use 
case for having a different namespace than the materialized view.
