I though tabout this, and it is really an issue for FDW authors, not for
end users, so I put this text in the Source Code changes section:

+        <para>
+         Foreign tables can now take part in <command>INSERT ... ON CONFLICT
+         DO NOTHING</> queries (Peter Geoghegan, Heikki Linnakangas,
+         Andres Freund)
+        </para>
+
+        <para>
+         Foreign data wrappers must be modified to handle this.
+         <command>INSERT ... ON CONFLICT DO UPDATE</> is not supported on
+         foreign tables.
+        </para>
+       </listitem>
