+    However, if you are upgrading from a version earlier than 7.4.11,
+    see the release notes for 7.4.11.

+     </para>
+
+     <para>
+      Before this fix, a negative constant in a view or rule might be dumped
+      as, say, <literal>-42::integer</>, which is subtly incorrect: it should
+      be <literal>(-42)::integer</> due to operator precedence rules.
+      Usually this would make little difference, but it could interact with
+      another recent patch to cause
+      <productname>PostgreSQL</> to reject what had been a valid
+      <command>SELECT DISTINCT</> view query.  Since this could result in
+      <application>pg_dump</> output failing to reload, it is being treated
+      as a high-priority fix.  The only released versions in which dump
+      output is actually incorrect are 8.3.1 and 8.2.7.
