-    While access to tables in the view is controlled entirely by permissions
-    on the view, functions called by the view are checked independently.
+    Access to tables referenced in the view is determined by permissions of
+    the view owner.  However, functions called in the view are treated the
+    same as if they had been called directly from the query using the view.
+    Therefore the user of a view must have permissions to call all functions
+    used by the view.
