+      When an underlying table is being accessed via a view, consider the
+      privileges of the view owner while deciding whether leaky operators
+      may be applied to the table's statistics data, rather than the
+      privileges of the user making the query.  This makes the planner's
+      rules about what data is visible match up with the executor's,
