      Fix infinite loops and buffer-overrun problems in regular expressions
      (Tom Lane)
     </p><p>
      Very large character ranges in bracket expressions could cause
      infinite loops in some cases, and memory overwrites in other cases.
      (CVE-2016-0773)
     </p></li><li class="listitem"><p>
      Fix an oversight that caused hash joins to miss joining to some tuples
      of the inner relation in rare cases (Tomas Vondra, Tom Lane)
     </p></li><li class="listitem"><p>
      Avoid pushdown of <code class="literal">HAVING</code> clauses when grouping sets are
      used (Andrew Gierth)
     </p></li><li class="listitem"><p>
      Fix deparsing of <code class="literal">ON CONFLICT</code> arbiter <code class="literal">WHERE</code>
      clauses (Peter Geoghegan)
     </p></li><li class="listitem"><p>
      Make <code class="literal">%h</code> and <code class="literal">%r</code> escapes
      in <code class="varname">log_line_prefix</code> work for messages emitted due
      to <code class="varname">log_connections</code> (Tom Lane)
     </p><p>
      Previously, <code class="literal">%h</code>/<code class="literal">%r</code> started to work just after a
      new session had emitted the <span class="quote">“<span class="quote">connection received</span>”</span> log message;
      now they work for that message too.

      Avoid leaking a token handle during SSPI authentication
      (Christian Ullrich)
     </p></li><li class="listitem"><p>
      Fix <span class="application">psql</span>'s <code class="literal">\det</code> command to interpret its

      In <span class="application">pg_ctl</span> on Windows, check service status to decide
      where to send output, rather than checking if standard output is a
      terminal (Michael Paquier)
     </p></li><li class="listitem"><p>
      Fix assorted corner-case bugs in <span class="application">pg_dump</span>'s processing
      of extension member objects (Tom Lane)
     </p></li><li class="listitem"><p>
      Fix improper quoting of domain constraint names
      in <span class="application">pg_dump</span> (Elvis Pranskevichus)
     </p></li><li class="listitem"><p>
      Make <span class="application">pg_dump</span> mark a view's triggers as needing to be
      processed after its rule, to prevent possible failure during
      parallel <span class="application">pg_restore</span> (Tom Lane)
     </p></li><li class="listitem"><p>
      Install guards in <span class="application">pgbench</span> against corner-case overflow
      conditions during evaluation of script-specified division or modulo
      operators (Fabien Coelho, Michael Paquier)
     </p></li><li class="listitem"><p>
      Suppress useless warning message when <span class="application">pg_receivexlog</span>

      Avoid dump/reload problems when using both <span class="application">plpython2</span>
      and <span class="application">plpython3</span> (Tom Lane)
     </p><p>
      In principle, both versions of <span class="application">PL/Python</span> can be used in
      the same database, though not in the same session (because the two
      versions of <span class="application">libpython</span> cannot safely be used concurrently).
      However, <span class="application">pg_restore</span> and <span class="application">pg_upgrade</span> both
      do things that can fall foul of the same-session restriction.  Work
      around that by changing the timing of the check.
     </p></li><li class="listitem"><p>
      Fix <span class="application">PL/Python</span> regression tests to pass with Python 3.5
      (Peter Eisentraut)
     </p></li><li class="listitem"><p>
      Prevent certain <span class="application">PL/Java</span> parameters from being set by
      non-superusers (Noah Misch)
     </p><p>
      This change mitigates a <span class="application">PL/Java</span> security bug
      (CVE-2016-0766), which was fixed in <span class="application">PL/Java</span> by marking
      these parameters as superuser-only.  To fix the security hazard for
      sites that update <span class="productname">PostgreSQL</span> more frequently
      than <span class="application">PL/Java</span>, make the core code aware of them also.
     </p></li><li class="listitem"><p>
      Fix <span class="application">ecpg</span>-supplied header files to not contain comments
      continued from a preprocessor directive line onto the next line
      (Michael Meskes)
     </p><p>
      Such a comment is rejected by <span class="application">ecpg</span>.  It's not yet clear
      whether <span class="application">ecpg</span> itself should be changed.
     </p></li><li class="listitem"><p>
      Fix <code class="function">hstore_to_json_loose()</code>'s test for whether
      an <code class="type">hstore</code> value can be converted to a JSON number (Tom Lane)
     </p><p>
      Previously this function could be fooled by non-alphanumeric trailing
      characters, leading to emitting syntactically-invalid JSON.
     </p></li><li class="listitem"><p>
      In <code class="filename">contrib/postgres_fdw</code>, fix bugs triggered by use

      Improve reproducibility of build output by ensuring filenames are given
      to the linker in a fixed order (Christoph Berg)
     </p><p>
      This avoids possible bitwise differences in the produced executable
      files from one build to the next.
     </p></li><li class="listitem"><p>
      Ensure that <code class="filename">dynloader.h</code> is included in the installed
