Newer versions of slon support a "-p" option which puts the PID into a file.

If you're not running something new enough (and that may be new to CVS
HEAD), then using ps to search for the pid is the way to go.

You cannot "recover" the node 1 cluster after dropping the node.

When the node is dropped, Slony-I drops the namespace, triggers, and
such, which erases nearly all traces of the node's existence. It does
this sufficiently thoroughly that you cannot recover it.

You will have to recreate the node from scratch, which will involve
copying over all of the replicated data.
