I have 2 nodes subscribed to a single master.
One of them had some issues at one point, and while new events appear to 
be replicating at the moment, there are somehow gaps in the dataset.

What's the easiest way to bring this rougue node back in line?
I assume there is no way to have slony 'analyze' the master node and 
generate events for the missing data from the subscriber.

Should I just unsubscribe the node, clear the data (back to the schema 
only) and then re-subscribe it?  (I shudder to think how long that might 
take).
Is that the right approach or is their a special slony/slon 
function/script I should be using to 're-synch' a node?

Thanks in advance.
