I think that you would be better off with multiple log files and multiple
sync_client processes, one for each replica. That way each replication
stream is independent and can progress at its own best speed.

Particularly important if a replica dies (or is shut down for routine 
maintenance) and needs to catch up from a big backlog of transactions.
