Should I specify that specifically in the instructions?
After running pg_upgrade I do put in new PGDATA on master old pg_hba.conf and postgresql.conf with wal_level = hot_standby. The full content of postgresql.conf could be seen here - http://pastie.org/9995902 <http://pastie.org/9995902>. Then I do rsync to replica, put recovery.conf and try to start both - first master, then replica. If I turn off hot_standby in replica configuration, it starts.
