       partition-level <command>TRUNCATE</command> on the referenced table,
       you should check to see if any foreign key violations exist.  The
-      simplest way is to drop and re-add the foreign key constraint,
-      though this may be unduly expensive.
+      simplest way is to add a new instance of the foreign key constraint
+      (and, once that succeeds, drop it or the original constraint).
+      That may be prohibitive from a locking standpoint, however, in which

+
+     <para>
+      When adding a partition to a level below the first level of a
+      multi-level partitioned table, foreign key constraints referencing
+      the top partitioned table were not cloned to the new partition,
+      leading to possible constraint violations later.  Detaching and
+      re-attaching the new partition is the cheapest way to fix this.
+      However, if there are many partitions to be fixed, adding a new
+      instance of the foreign key constraint might be preferable.
