+ Tables or foreign tables which are partitions of some other table are
+ automatically excluded. Partitioned tables are imported, unless they
+ are a partition of some other table. Since all data can be accessed
+ through the partitioned table which is the root of the partitioning
+ hierarchy, this approach should allow access to all the data without
+ creating extra objects.
