Third pass on 9.6.3 release notes.

Add updates for recent commits.

In passing, credit Etsuro Fujita for his work on the postgres_fdw
query cancel feature in 9.6; I seem to have missed that in the
original drafting of the 9.6 notes.

+      Use correct daylight-savings rules for POSIX-style time zone names

+     </para>
+
+     <para>
+      The Microsoft MSVC build scripts neglected to install
+      the <filename>posixrules</> file in the timezone directory tree.
+      This resulted in the timezone code falling back to its built-in
+      rule about what DST behavior to assume for a POSIX-style time zone
+      name.  For historical reasons that still corresponds to the DST rules
+      the USA was using before 2007 (i.e., change on first Sunday in April
+      and last Sunday in October).  With this fix, a POSIX-style zone name
+      will use the current and historical DST transition dates of
+      the <literal>US/Eastern</> zone.  If you don't want that, remove
+      the <filename>posixrules</> file, or replace it with a copy of some
+      other zone file (see <xref linkend="datatype-timezones">).  Note that
+      due to caching, you may need to restart the server to get such changes
+      to take effect.
