+      User-defined objects that reference some built-in array functions
+      along with their argument types must be recreated (Tom Lane)

+      Specifically, 
+      linkend="functions-array">array_append(),
+      array_prepend(),
+      array_cat(),
+      array_position(),
+      array_positions(),
+      array_remove(),
+      array_replace(), or 
+      linkend="functions-math">width_bucket()
+      used to take anyarray arguments but now take
+      anycompatiblearray.  Therefore, user-defined objects
+      like aggregates and operators that reference old array function
+      signatures must be dropped before upgrading and recreated once the
+      upgrade completes.
