    A dump/restore is not required for those running 8.3.X.
    However, if you are upgrading from a version earlier than 8.3.8,
    see <a class="xref" href="release-8-3-8.html" title="E.197. Release 8.3.8">Section E.197</a>.

      Disallow including a composite type in itself (Tom Lane)
     </p><p>
      This prevents scenarios wherein the server could recurse infinitely
      while processing the composite type.  While there are some possible
      uses for such a structure, they don't seem compelling enough to
      justify the effort required to make sure it always works safely.

      Avoid potential deadlock during catalog cache initialization
      (Nikhil Sontakke)
     </p><p>
      In some cases the cache loading code would acquire share lock on a
      system index before locking the index's catalog.  This could deadlock
      against processes trying to acquire exclusive locks in the other,
      more standard order.
     </p></li><li class="listitem"><p>
      Fix dangling-pointer problem in <code class="literal">BEFORE ROW UPDATE</code> trigger
      handling when there was a concurrent update to the target tuple
      (Tom Lane)
     </p><p>
      This bug has been observed to result in intermittent <span class="quote">“<span class="quote">cannot
      extract system attribute from virtual tuple</span>”</span> failures while trying to
      do <code class="literal">UPDATE RETURNING ctid</code>.  There is a very small probability
      of more serious errors, such as generating incorrect index entries for
      the updated tuple.
     </p></li><li class="listitem"><p>
      Disallow <code class="command">DROP TABLE</code> when there are pending deferred trigger
      events for the table (Tom Lane)
     </p><p>
      Formerly the <code class="command">DROP</code> would go through, leading to
      <span class="quote">“<span class="quote">could not open relation with OID nnn</span>”</span> errors when the
      triggers were eventually fired.
     </p></li><li class="listitem"><p>
      Fix PL/Python memory leak involving array slices (Daniel Popowich)
     </p></li><li class="listitem"><p>
      Fix <span class="application">pg_restore</span> to cope with long lines (over 1KB) in
      TOC files (Tom Lane)
     </p></li><li class="listitem"><p>
      Put in more safeguards against crashing due to division-by-zero
      with overly enthusiastic compiler optimization (Aurelien Jarno)
     </p></li><li class="listitem"><p>
      Support use of dlopen() in FreeBSD and OpenBSD on MIPS (Tom Lane)
     </p><p>
      There was a hard-wired assumption that this system function was not
      available on MIPS hardware on these systems.  Use a compile-time test
      instead, since more recent versions have it.
     </p></li><li class="listitem"><p>
      Fix compilation failures on HP-UX (Heikki Linnakangas)
     </p></li><li class="listitem"><p>
      Fix version-incompatibility problem with <span class="application">libintl</span> on
      Windows (Hiroshi Inoue)
     </p></li><li class="listitem"><p>
      Fix usage of <span class="application">xcopy</span> in Windows build scripts to
      work correctly under Windows 7 (Andrew Dunstan)
     </p><p>
      This affects the build scripts only, not installation or usage.

      Fix path separator used by <span class="application">pg_regress</span> on Cygwin
      (Andrew Dunstan)

      Update time zone data files to <span class="application">tzdata</span> release 2011f
      for DST law changes in Chile, Cuba, Falkland Islands, Morocco, Samoa,
      and Turkey; also historical corrections for South Australia, Alaska,
      and Hawaii.
