   This release contains a small number of fixes from 9.6.4.
   For information about new features in the 9.6 major release, see
   <a class="xref" href="release-9-6.html" title="E.21. Release 9.6">Section E.21</a>.

    A dump/restore is not required for those running 9.6.X.
   </p><p>
    However, if you are upgrading from a version earlier than 9.6.4,
    see <a class="xref" href="release-9-6-4.html" title="E.17. Release 9.6.4">Section E.17</a>.

      Clean up handling of a fatal exit (e.g., due to receipt
      of <span class="systemitem">SIGTERM</span>) that occurs while trying to execute
      a <code class="command">ROLLBACK</code> of a failed transaction (Tom Lane)
     </p><p>
      This situation could result in an assertion failure.  In production
      builds, the exit would still occur, but it would log an unexpected
      message about <span class="quote">“<span class="quote">cannot drop active portal</span>”</span>.

      Correctly identify columns that are of a range type or domain type over
      a composite type or domain type being searched for (Tom Lane)
     </p><p>
      Certain <code class="command">ALTER</code> commands that change the definition of a
      composite type or domain type are supposed to fail if there are any
      stored values of that type in the database, because they lack the
      infrastructure needed to update or check such values.  Previously,
      these checks could miss relevant values that are wrapped inside range
      types or sub-domains, possibly allowing the database to become
      inconsistent.

      Change <span class="application">ecpg</span>'s parser to allow <code class="literal">RETURNING</code>
      clauses without attached C variables (Michael Meskes)
     </p><p>
      This allows <span class="application">ecpg</span> programs to contain SQL constructs
      that use <code class="literal">RETURNING</code> internally (for example, inside a CTE)
      rather than using it to define values to be returned to the client.

      Improve selection of compiler flags for PL/Perl on Windows (Tom Lane)
     </p><p>
      This fix avoids possible crashes of PL/Perl due to inconsistent
      assumptions about the width of <code class="type">time_t</code> values.
      A side-effect that may be visible to extension developers is
      that <code class="literal">_USE_32BIT_TIME_T</code> is no longer defined globally
      in <span class="productname">PostgreSQL</span> Windows builds.  This is not expected
      to cause problems, because type <code class="type">time_t</code> is not used
      in any <span class="productname">PostgreSQL</span> API definitions.
