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>
