Hola Martin
Pues si uno sigue la secuencia de la pagina de ayuda de PostgreSQL
Usage
(...)
7. Stop both servers
(...)
10. Upgrade Streaming Replication and Log-Shipping standby servers
(...)
12. Start the new server
The new server can now be safely started, and then any rsync'ed standby servers.
Pensaría que toca esperar a que terminen todo los rsync de las replicas antes de iniciar la master... Pero tengo incluso una pregunta adicional: si tengo 2 o mas replicas.. se podria sincronizar primero la master con una replica (rsync), iniciar la master y luego emplear la replica sincronizada para sincronizar el resto de replicas mientras que la máster ya se encuentra en funcionamiento?.

Immediately following, you can read:
If you did not use link mode, do not have or do not want to use rsync, or want an easier
solution, skip the instructions in this section and simply recreate the standby servers
once pg_upgrade completes and the new primary is running.
So this is not compulsory, it's just an efficient method to quickly get the standby
server updated.
There is nothing wrong with rebuilding the standby later.
