+ <para>
+ Properly reject attempts to convert infinite float values to
+ type <type>numeric</type> (Tom Lane, KaiGai Kohei)
+ </para>
+
+ <para>
+ Previously the behavior was platform-dependent.
+ </para>
+ </listitem>
+
+ <listitem>
+ <para>
+ Fix corner-case crashes when columns have been added to the end of a
+ view (Tom Lane)
+ </para>
+ </listitem>
+
+ <listitem>
+ <para>
+ Record proper dependencies when a view or rule
+ contains <structname>FieldSelect</structname>
+ or <structname>FieldStore</structname> expression nodes (Tom Lane)
+ </para>
+
+ <para>
+ Lack of these dependencies could allow a column or data
+ type <command>DROP</command> to go through when it ought to fail,
+ thereby causing later uses of the view or rule to get errors.
+ This patch does not do anything to protect existing views/rules,
+ only ones created in the future.
+ </para>
+ </listitem>
+
+ <listitem>
+ <para>
+ Correctly detect hashability of range data types (Tom Lane)
+ </para>
+
+ <para>
+ The planner mistakenly assumed that any range type could be hashed
+ for use in hash joins or hash aggregation, but actually it must check
+ whether the range's subtype has hash support. This does not affect any
+ of the built-in range types, since they're all hashable anyway.
+ </para>
+ </listitem>
+
+ <listitem>
+ <para>
+ Fix low-probability loss of <command>NOTIFY</command> messages due to
+ XID wraparound (Marko Tiikkaja, Tom Lane)
+ </para>
+
+ <para>
+ If a session executed no queries, but merely listened for
+ notifications, for more than 2 billion transactions, it started to miss
+ some notifications from concurrently-committing transactions.
+ </para>
+ </listitem>

+ <para>
+ Prevent low-probability crash in processing of nested trigger firings
+ (Tom Lane)
+ </para>
+ </listitem>
+
+ <listitem>
+ <para>
+ Correctly restore the umask setting when file creation fails
+ in <command>COPY</command> or <function>lo_export()</function>
+ (Peter Eisentraut)
+ </para>
+ </listitem>
+
+ <listitem>
+ <para>
+ Give a better error message for duplicate column names
+ in <command>ANALYZE</command> (Nathan Bossart)
+ </para>
+ </listitem>
+
+ <listitem>
+ <para>
+ Fix <application>libpq</application> to not require user's home
+ directory to exist (Tom Lane)
+ </para>
+
+ <para>
+ In v10, failure to find the home directory while trying to
+ read <filename>~/.pgpass</filename> was treated as a hard error,
+ but it should just cause that file to not be found. Both v10 and
+ previous release branches made the same mistake when
+ reading <filename>~/.pg_service.conf</filename>, though this was less
+ obvious since that file is not sought unless a service name is
+ specified.
+ </para>
+ </listitem>
+
+ <listitem>
+ <para>
+ Fix <application>libpq</application> to guard against integer
+ overflow in the row count of a <structname>PGresult</structname>
+ (Michael Paquier)
+ </para>
+ </listitem>
+
+ <listitem>
+ <para>
+ Sync our copy of the timezone library with IANA release tzcode2017c
+ (Tom Lane)
+ </para>
+
+ <para>
+ This fixes various issues; the only one likely to be user-visible
+ is that the default DST rules for a POSIX-style zone name, if
+ no <filename>posixrules</filename> file exists in the timezone data
+ directory, now match current US law rather than what it was a dozen
+ years ago.
+ </para>
+ </listitem>
+
+ <listitem>
+ <para>
+ Update time zone data files to <application>tzdata</application>
+ release 2017c for DST law changes in Fiji, Namibia, Northern Cyprus,
+ Sudan, Tonga, and Turks & Caicos Islands, plus historical
+ corrections for Alaska, Apia, Burma, Calcutta, Detroit, Ireland,
+ Namibia, and Pago Pago.
