   This release contains fixes from 7.4.16,
   including a security fix.
   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 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>.

     Support explicit placement of the temporary-table schema within
     <code class="varname">search_path</code>, and disable searching it for functions
     and operators (Tom)
    </p><p>
     This is needed to allow a security-definer function to set a
     truly secure value of <code class="varname">search_path</code>.  Without it,
     an unprivileged SQL user can use temporary objects to execute code
     with the privileges of the security-definer function (CVE-2007-2138).
     See <code class="command">CREATE FUNCTION</code> for more information.
