I think there may be a terminology issue here -- I took "configure
by standby" to mean that *at the master* you would specify rules for
each standby.  I think Simon took it to mean that each standby would
define the rules for replication to it.  Maybe this issue can
resolve gracefully with a bit of clarification?
