I think so. There is some problem in pg_upgrade documentation, nothing about:
1. preventing heap change by vacuum, analyze, something also when master  restarted after pg_upgrade but before rsync
2. log-shipping only standby cannot shutdown at the same checkpoint with  master

I try to start discuss about this: https://www.postgresql.org/message-id/87y3ta49zp.fsf%40seb.koffice.internal
but without luck :-)

PS: I CC'd Bruce here.
