You can't.  Slony-I doesn't support that kind of usage.

If you truly need to replicate an entire database cluster, then you
should look into PITR, aka "warm standby."

The documentation describes how to do this in some detail:
    <http://slony.info/documentation/addthings.html>

If that isn't clear enough, then it would be most useful to try to
make the documentation better, as that will help many users.
