docs(changeset): When the PostgreSQL LISTEN is interrupted (networking issue/server restart/etc), subscriptions will now be TERMINATED. This is a change in behavior to ensure that messages are not dropped without client knowledge - we want at-least-once delivery, and if we can't guarantee that we should terminate the subscription so the client can perform any necessary resynchronization.
