+      Clear the OpenSSL error queue before OpenSSL calls, rather than
+      assuming it's clear already; and make sure we leave it clear
+      afterwards (Peter Geoghegan, Dave Vitek, Peter Eisentraut)
+     </para>
+
+     <para>
+      This change prevents problems when there are multiple connections
+      using OpenSSL within a single process and not all the code involved
+      follows the same rules for when to clear the error queue.
+      Failures have been reported specifically when a client application
+      uses SSL connections in <application>libpq</> concurrently with
+      SSL connections using the PHP, Python, or Ruby wrappers for OpenSSL.
+      It's possible for similar problems to arise within the server as well,
+      if an extension module establishes an outgoing SSL connection.

+      Fix possible misbehavior of <literal>TH</>, <literal>th</>,

+      (Tom Lane)
+     </para>
+
+     <para>
+      These could advance off the end of the input string, causing subsequent
+      format codes to read garbage.

+      Fix dumping of rules and views in which the <replaceable>array</>

+      ANY (<replaceable>array</>)</literal> construct is a sub-SELECT

+      Make <application>pg_regress</> use a startup timeout from the
+      <envar>PGCTLTIMEOUT</> environment variable, if that's set (Tom Lane)
+     </para>
+
+     <para>
+      This is for consistency with a behavior recently added
+      to <application>pg_ctl</>; it eases automated testing on slow machines.

+     <para>
+      Fix <application>pg_upgrade</> to correctly restore extension
+      membership for operator families containing only one operator class
+      (Tom Lane)
+     </para>
+
+     <para>
+      In such a case, the operator family was restored into the new database,
+      but it was no longer marked as part of the extension.  This had no
+      immediate ill effects, but would cause later <application>pg_dump</>
+      runs to emit output that would cause (harmless) errors on restore.

+      Rename internal function <function>strtoi()</>

+      function (Thomas Munro)

+      Use the <literal>FORMAT_MESSAGE_IGNORE_INSERTS</> flag where

+      Update time zone data files to <application>tzdata</> release 2016d
+      for DST law changes in Russia and Venezuela.  There are new zone
+      names <literal>Europe/Kirov</> and <literal>Asia/Tomsk</> to reflect
+      the fact that these regions now have different time zone histories from
+      adjacent regions.
