The current documentation of session_replication_role GUC is:

    Controls firing of replication-related triggers and rules for the
    current session. Setting this variable requires superuser privilege
    and results in discarding any previously cached query plans.
    Possible values are origin (the default), replica and local.
    See ALTER TABLE for more information.

It doesn't speak about foreign keys or referential integrity, but only
about triggers and rules. I don't think that it's worth to add a special
case for truncate, unless we want to expand/rewrite the documentation to
specify all the effects in the details.

Regards,
Marco
