   This release contains a variety of fixes from 8.3.7.
   For information about new features in the 8.3 major release, see
   <a class="xref" href="release-8-3.html" title="E.205. Release 8.3">Section E.205</a>.

    A dump/restore is not required for those running 8.3.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 8.3.8.
    Also, if you are upgrading from a version earlier than 8.3.5,
    see <a class="xref" href="release-8-3-5.html" title="E.200. Release 8.3.5">Section E.200</a>.

      Fix Windows shared-memory allocation code (Tsutomu Yamada, Magnus)
     </p><p>
      This bug led to the often-reported <span class="quote">“<span class="quote">could not reattach
      to shared memory</span>”</span> error message.
     </p></li><li class="listitem"><p>
      Force WAL segment switch during <code class="function">pg_start_backup()</code>
      (Heikki)
     </p><p>
      This avoids corner cases that could render a base backup unusable.
     </p></li><li class="listitem"><p>
      Disallow <code class="command">RESET ROLE</code> and <code class="command">RESET SESSION
      AUTHORIZATION</code> inside security-definer functions (Tom, Heikki)
     </p><p>
      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.
      (See CVE-2007-6600)
     </p></li><li class="listitem"><p>
      Make <code class="command">LOAD</code> of an already-loaded loadable module
      into a no-op (Tom)
     </p><p>
      Formerly, <code class="command">LOAD</code> would attempt to unload and re-load the
      module, but this is unsafe and not all that useful.
     </p></li><li class="listitem"><p>
      Disallow empty passwords during LDAP authentication (Magnus)
     </p></li><li class="listitem"><p>
      Fix handling of sub-SELECTs appearing in the arguments of
      an outer-level aggregate function (Tom)
     </p></li><li class="listitem"><p>
      Fix bugs associated with fetching a whole-row value from the
      output of a Sort or Materialize plan node (Tom)
     </p></li><li class="listitem"><p>

      scrollable and <code class="literal">WITH HOLD</code> cursors (Tom)
     </p></li><li class="listitem"><p>
      Revert planner change that disabled partial-index and constraint
      exclusion optimizations when there were more than 100 clauses in
      an AND or OR list (Tom)
     </p></li><li class="listitem"><p>
      Fix hash calculation for data type <code class="type">interval</code> (Tom)
     </p><p>
      This corrects wrong results for hash joins on interval values.
      It also changes the contents of hash indexes on interval columns.
      If you have any such indexes, you must <code class="command">REINDEX</code> them
      after updating.
     </p></li><li class="listitem"><p>
      Treat <code class="function">to_char(..., 'TH')</code> as an uppercase ordinal
      suffix with <code class="literal">'HH'</code>/<code class="literal">'HH12'</code> (Heikki)
     </p><p>
      It was previously handled as <code class="literal">'th'</code> (lowercase).
     </p></li><li class="listitem"><p>
      Fix overflow for <code class="literal">INTERVAL '<em class="replaceable"><code>x</code></em> ms'</code>

      datetimes are in use (Alex Hunsaker)
     </p></li><li class="listitem"><p>
      Fix calculation of distance between a point and a line segment (Tom)

      amounts have no fractional digits, e.g. Japan (Itagaki Takahiro)

      (Tom)
     </p></li><li class="listitem"><p>
      Properly round datetime input like

      Improve <span class="application">pg_dump</span>'s efficiency when there are
