Log Message

Bug 136
    When a forwarding node goes away a dba might issue a subscribe set to reshape the
    cluster so the receiver gets the data from a different provider.
    It could be the case that the receiver never sees the SUBSCRIBE_SET event
    because it is only listening on events from the origin from the forwarder
    that has gone away.

    If we are reshaping a cluster then slonik will contact the receiver
    directly and run update sl_subscribe so the receiver can
    listen from the correct source.
