I have tried to find a test but not able to find one. I have tried
with a foreign table but we don't log truncate for it, see
ExecuteTruncate. It has a check that it will log for relids where
RelationIsLogicallyLogged. If that is the case, it is not clear to me
how we can ever hit this condition? Have you tried to find the test?
