>From the docs: 
cases where Slony-I probably won't work out well would include:

      * Sites where connectivity is really "flakey"
        
      * Replication to nodes that are unpredictably connected.

How flakey/unpredictably connected can nodes be before it all goes
haywire?  Is it time critical, or load critical?  If an origin node goes
offline for a day, but there are only a couple of transactions, will
that be a problem?  If an origin node goes offline for a few minutes but
there are hundreds of transactions, what's the recovery scenario look
like?

Thanks,
