> > I think I've narrowed it down to Slony and Mammoth. > Any pro's or con's on one vs the other? Slony is more complicated to setup. Slony requires triggers and cron. Slony is asynchronous Slony is Open Source If Slony breaks you can call Command Prompt It used to be that Slony was timed replication. I do not know if that is still the case. Mammoth is about as easy as it can be to setup. Mammoth does not require triggers or cron Mammoth is asynchronous Mammoth costs $$$ Mammoth is set to be optionally synchronous in June. Mammoth replicates on a per comitted transaction basis. Mammoth Replicator is PostgreSQL with integrated replication. If Mammoth breaks you can call Command Prompt ;) > > Some area where our environement might stretch a solution. > Some records can be large.

Neither Mammoth or Slony require any exclusive locks to replicate the data. Sincerely, Joshua D.
