Unless we can make the standby.conf files identical on all servers in
the group. If we can do that, then conf file management utilities,
fileshares, or a simple automated rsync could easily take care of things.
But ... any setup which involves each standby being *required* to have a
different configuration on each standby server, which has to be edited
separately, is going to be fatally difficult to manage for anyone who
has more than a couple of standbys. So I'd like to look at what it
takes to get away from that.
