I don't think any of this quorum stuff makes much sense without explicitly
registering standbys in the master.
This doesn't have to be done manually. The streaming protocol could
include the standby sending its system id to the master. The master
could just keep a list of system ids with the last record they've been
sent and the last they've confirmed receipt, fsync, application,
whatever the protocol covers. If the same system reconnects it just
overwrites the existing data for that system id.
Systemid doesn't work for that. Systemid is assigned at initdb time, so
all the standbys have the same systemid as the master.
