Foreign tables do not have physical storage assigned to by default. At
least heap_create() tells so, create_storage being set to false for a
foreign table. So there is nothing to clean up normally. Or is
cstore_fdw using directly heap_create with its own relfilenode set,
creating a physical storage?

cstore_fdw (in store_data_in_internal_storage branch) calls RelationCreateStorage() after CREATE FOREIGN TABLE completes [1]. Later it also creates the FSM fork and uses it for storing some metadata.
