   This release contains a small number of fixes from 9.2.12.
   For information about new features in the 9.2 major release, see
   <a class="xref" href="release-9-2.html" title="E.109. Release 9.2">Section E.109</a>.

    A dump/restore is not required for those running 9.2.X.
   </p><p>
    However, if you are upgrading from a version earlier than 9.2.11,
    see <a class="xref" href="release-9-2-11.html" title="E.98. Release 9.2.11">Section E.98</a>.

      Fix rare failure to invalidate relation cache init file (Tom Lane)
     </p><p>
      With just the wrong timing of concurrent activity, a <code class="command">VACUUM
      FULL</code> on a system catalog might fail to update the <span class="quote">“<span class="quote">init file</span>”</span>
      that's used to avoid cache-loading work for new sessions.  This would
      result in later sessions being unable to access that catalog at all.
      This is a very ancient bug, but it's so hard to trigger that no
      reproducible case had been seen until recently.
     </p></li><li class="listitem"><p>
      Avoid deadlock between incoming sessions and <code class="literal">CREATE/DROP
      DATABASE</code> (Tom Lane)
     </p><p>
      A new session starting in a database that is the target of
      a <code class="command">DROP DATABASE</code> command, or is the template for
      a <code class="command">CREATE DATABASE</code> command, could cause the command to wait
      for five seconds and then fail, even if the new session would have
      exited before that.
