   This release contains a variety of fixes from 7.4.25.
   For information about new features in the 7.4 major release, see
   <a class="xref" href="release-7-4.html" title="E.311. Release 7.4">Section E.311</a>.

    A dump/restore is not required for those running 7.4.X.
    However, if you have any hash indexes on <code class="type">interval</code> columns,
    you must <code class="command">REINDEX</code> them after updating to 7.4.26.
    Also, if you are upgrading from a version earlier than 7.4.11,
    see <a class="xref" href="release-7-4-11.html" title="E.300. Release 7.4.11">Section E.300</a>.

      AUTHORIZATION</code> inside security-definer functions (Tom, Heikki)

      This covers a case that was missed in the previous patch that
      disallowed <code class="command">SET ROLE</code> and <code class="command">SET SESSION
      AUTHORIZATION</code> inside security-definer functions.

      This corrects wrong results for hash joins on interval values.

      after updating.
