Hi,

The current behavior of session_replication_role = replica with TRUNCATE
is not the same of with the other commands.
It does not check FKs for INSERT/UPDATE/DELETE but it does for TRUNCATE,
so one cannot execute TRUNCATE on a table when it is possible to DELETE
from table without WHERE clause.

I'm attaching a simple patch to make TRUNCATE match behavior of DELETE
for session_replication_role = replica.

Regards,
Marco
