   <a class="xref" href="release-8-2.html" title="E.229. Release 8.2">Section E.229</a>.
  </p><p>
   The <span class="productname">PostgreSQL</span> community will stop releasing updates
   for the 8.2.X release series in December 2011.
   Users are encouraged to update to a newer release branch soon.

    A dump/restore is not required for those running 8.2.X.
    However, if you are upgrading from a version earlier than 8.2.14,
    see <a class="xref" href="release-8-2-14.html" title="E.215. Release 8.2.14">Section E.215</a>.

      Fix multiple bugs in GiST index page split processing (Heikki
      Linnakangas)
     </p><p>
      The probability of occurrence was low, but these could lead to index
      corruption.
     </p></li><li class="listitem"><p>
      Avoid possibly accessing off the end of memory in <code class="command">ANALYZE</code>
      (Noah Misch)
     </p><p>
      This fixes a very-low-probability server crash scenario.
     </p></li><li class="listitem"><p>
      Fix race condition in relcache init file invalidation (Tom Lane)
     </p><p>
      There was a window wherein a new backend process could read a stale init
      file but miss the inval messages that would tell it the data is stale.
      The result would be bizarre failures in catalog accesses, typically
      <span class="quote">“<span class="quote">could not read block 0 in file ...</span>”</span> later during startup.
     </p></li><li class="listitem"><p>
      Fix memory leak at end of a GiST index scan (Tom Lane)
     </p><p>
      Commands that perform many separate GiST index scans, such as
      verification of a new GiST-based exclusion constraint on a table
      already containing many rows, could transiently require large amounts of
      memory due to this leak.
     </p></li><li class="listitem"><p>
      Fix performance problem when constructing a large, lossy bitmap
      (Tom Lane)
     </p></li><li class="listitem"><p>
      Fix array- and path-creating functions to ensure padding bytes are
      zeroes (Tom Lane)
     </p><p>
      This avoids some situations where the planner will think that
      semantically-equal constants are not equal, resulting in poor
      optimization.
     </p></li><li class="listitem"><p>
      Work around gcc 4.6.0 bug that breaks WAL replay (Tom Lane)
     </p><p>
      This could lead to loss of committed transactions after a server crash.
     </p></li><li class="listitem"><p>
      Fix dump bug for <code class="literal">VALUES</code> in a view (Tom Lane)
     </p></li><li class="listitem"><p>
      Disallow <code class="literal">SELECT FOR UPDATE/SHARE</code> on sequences (Tom Lane)
     </p><p>
      This operation doesn't work as expected and can lead to failures.
     </p></li><li class="listitem"><p>
      Defend against integer overflow when computing size of a hash table (Tom
      Lane)
     </p></li><li class="listitem"><p>
      Fix portability bugs in use of credentials control messages for
      <span class="quote">“<span class="quote">peer</span>”</span> authentication (Tom Lane)
     </p></li><li class="listitem"><p>
      Fix typo in <code class="function">pg_srand48</code> seed initialization (Andres Freund)
     </p><p>
      This led to failure to use all bits of the provided seed.  This function
      is not used on most platforms (only those without <code class="function">srandom</code>),
      and the potential security exposure from a less-random-than-expected
      seed seems minimal in any case.
     </p></li><li class="listitem"><p>
      Avoid integer overflow when the sum of <code class="literal">LIMIT</code> and
      <code class="literal">OFFSET</code> values exceeds 2^63 (Heikki Linnakangas)
     </p></li><li class="listitem"><p>
      Add overflow checks to <code class="type">int4</code> and <code class="type">int8</code> versions of
      <code class="function">generate_series()</code> (Robert Haas)
     </p></li><li class="listitem"><p>
      Fix trailing-zero removal in <code class="function">to_char()</code> (Marti Raudsepp)
     </p><p>
      In a format with <code class="literal">FM</code> and no digit positions
      after the decimal point, zeroes to the left of the decimal point could
      be removed incorrectly.
     </p></li><li class="listitem"><p>
      Fix <code class="function">pg_size_pretty()</code> to avoid overflow for inputs close to
      2^63 (Tom Lane)
     </p></li><li class="listitem"><p>
      Fix <span class="application">psql</span>'s counting of script file line numbers during
      <code class="literal">COPY</code> from a different file (Tom Lane)
     </p></li><li class="listitem"><p>
      Fix <span class="application">pg_restore</span>'s direct-to-database mode for
      <code class="varname">standard_conforming_strings</code> (Tom Lane)
     </p><p>
      <span class="application">pg_restore</span> could emit incorrect commands when restoring
      directly to a database server from an archive file that had been made
      with <code class="varname">standard_conforming_strings</code> set to <code class="literal">on</code>.
     </p></li><li class="listitem"><p>
      Fix write-past-buffer-end and memory leak in <span class="application">libpq</span>'s
      LDAP service lookup code (Albe Laurenz)
     </p></li><li class="listitem"><p>
      In <span class="application">libpq</span>, avoid failures when using nonblocking I/O
      and an SSL connection (Martin Pihlak, Tom Lane)
     </p></li><li class="listitem"><p>
      Improve libpq's handling of failures during connection startup
      (Tom Lane)
     </p><p>
      In particular, the response to a server report of <code class="function">fork()</code>
      failure during SSL connection startup is now saner.
     </p></li><li class="listitem"><p>
      Make <span class="application">ecpglib</span> write <code class="type">double</code> values with 15 digits
      precision (Akira Kurosawa)
     </p></li><li class="listitem"><p>
      Apply upstream fix for blowfish signed-character bug (CVE-2011-2483)
      (Tom Lane)
     </p><p>
      <code class="filename">contrib/pg_crypto</code>'s blowfish encryption code could give
      wrong results on platforms where char is signed (which is most),
      leading to encrypted passwords being weaker than they should be.
     </p></li><li class="listitem"><p>
      Fix memory leak in <code class="filename">contrib/seg</code> (Heikki Linnakangas)
     </p></li><li class="listitem"><p>
      Fix <code class="function">pgstatindex()</code> to give consistent results for empty
      indexes (Tom Lane)
     </p></li><li class="listitem"><p>
      Allow building with perl 5.14 (Alex Hunsaker)
     </p></li><li class="listitem"><p>
      Update configure script's method for probing existence of system
      functions (Tom Lane)
     </p><p>
      The version of autoconf we used in 8.3 and 8.2 could be fooled by
      compilers that perform link-time optimization.
     </p></li><li class="listitem"><p>
      Fix assorted issues with build and install file paths containing spaces
      (Tom Lane)
     </p></li><li class="listitem"><p>
      Update time zone data files to <span class="application">tzdata</span> release 2011i
      for DST law changes in Canada, Egypt, Russia, Samoa, and South Sudan.
