> This is the case where the events were deleted on source because of old event 
> purging and hence min(source event id) > target event id (last replicated 
> event id).
> Repl dump should fail in this case so that user can drop the database and 
> bootstrap again.
> The next incremental repl dump could check if the events fetched from source 
> notification_log table is retrieved in continuous sequence with no events 
> missing. If any event is missing, it should throw error.
