   This release contains a variety of fixes from 8.0.23.
   For information about new features in the 8.0 major release, see
   <a class="xref" href="release-8-0.html" title="E.280. Release 8.0">Section E.280</a>.
  </p><p>
   The <span class="productname">PostgreSQL</span> community will stop releasing updates
   for the 8.0.X release series in July 2010.
   Users are encouraged to update to a newer release branch soon.

    A dump/restore is not required for those running 8.0.X.
    However, if you are upgrading from a version earlier than 8.0.22,
    see <a class="xref" href="release-8-0-22.html" title="E.258. Release 8.0.22">Section E.258</a>.

      Add new configuration parameter <code class="varname">ssl_renegotiation_limit</code> to
      control how often we do session key renegotiation for an SSL connection
      (Magnus)
     </p><p>
      This can be set to zero to disable renegotiation completely, which may
      be required if a broken SSL library is used.  In particular, some
      vendors are shipping stopgap patches for CVE-2009-3555 that cause
      renegotiation attempts to fail.
     </p></li><li class="listitem"><p>
      Fix possible crashes when trying to recover from a failure in
      subtransaction start (Tom)
     </p></li><li class="listitem"><p>
      Fix server memory leak associated with use of savepoints and a client
      encoding different from server's encoding (Tom)
     </p></li><li class="listitem"><p>
      Make <code class="function">substring()</code> for <code class="type">bit</code> types treat any negative
      length as meaning <span class="quote">“<span class="quote">all the rest of the string</span>”</span> (Tom)
     </p><p>
      The previous coding treated only -1 that way, and would produce an
      invalid result value for other negative values, possibly leading to
      a crash (CVE-2010-0442).
     </p></li><li class="listitem"><p>
      Fix integer-to-bit-string conversions to handle the first fractional
      byte correctly when the output bit width is wider than the given
      integer by something other than a multiple of 8 bits (Tom)
     </p></li><li class="listitem"><p>
      Fix some cases of pathologically slow regular expression matching (Tom)
     </p></li><li class="listitem"><p>
      Fix the <code class="literal">STOP WAL LOCATION</code> entry in backup history files to
      report the next WAL segment's name when the end location is exactly at a
      segment boundary (Itagaki Takahiro)
     </p></li><li class="listitem"><p>
      When reading <code class="filename">pg_hba.conf</code> and related files, do not treat
      <code class="literal">@something</code> as a file inclusion request if the <code class="literal">@</code>
      appears inside quote marks; also, never treat <code class="literal">@</code> by itself
      as a file inclusion request (Tom)
     </p><p>
      This prevents erratic behavior if a role or database name starts with
      <code class="literal">@</code>.  If you need to include a file whose path name
      contains spaces, you can still do so, but you must write
      <code class="literal">@"/path to/file"</code> rather than putting the quotes around
      the whole construct.
     </p></li><li class="listitem"><p>
      Prevent infinite loop on some platforms if a directory is named as
      an inclusion target in <code class="filename">pg_hba.conf</code> and related files
      (Tom)
     </p></li><li class="listitem"><p>
      Fix plpgsql failure in one case where a composite column is set to NULL
      (Tom)
     </p></li><li class="listitem"><p>
      Add <code class="literal">volatile</code> markings in PL/Python to avoid possible
      compiler-specific misbehavior (Zdenek Kotala)
     </p></li><li class="listitem"><p>
      Ensure PL/Tcl initializes the Tcl interpreter fully (Tom)
     </p><p>
      The only known symptom of this oversight is that the Tcl
      <code class="literal">clock</code> command misbehaves if using Tcl 8.5 or later.
     </p></li><li class="listitem"><p>
      Prevent crash in <code class="filename">contrib/dblink</code> when too many key
      columns are specified to a <code class="function">dblink_build_sql_*</code> function
      (Rushabh Lathia, Joe Conway)
     </p></li><li class="listitem"><p>
      Fix assorted crashes in <code class="filename">contrib/xml2</code> caused by sloppy
      memory management (Tom)
     </p></li><li class="listitem"><p>
      Update time zone data files to <span class="application">tzdata</span> release 2010e
      for DST law changes in Bangladesh, Chile, Fiji, Mexico, Paraguay, Samoa.
