So now we have to check *all* of the standby logs in order to check that
replication on the master is working without problems. There will be no
default capability to tie up events on the master with failures of
replication. Events occurring on multiple standbys will not be picked up
as a correlated set of events.
It's possible, but its not a realistic alternative.
We've lost something and gained almost nothing. We need to avoid making
this kind of improvement.
