No. I guess the most possible partitioning scheme would be schema-based so each schema's objects are created on their own partitioned catalogs and the name-based search mechanism would append a where clause to the search limit the schemas that are search based upon the current search_path. Since the catalogs are cluster shared having a partition be database-schema name based would be even more appropriate. Note I'm not even sure if catalog access in this way is done via SQL or by some other mechanism that would not be readily partitioned.
