Thanks.
This has the following two problems.* pg_start_backup() must set 'on' to full_page_writes of the master that is
actualwriting of the WAL, but not the standby.* The standby doesn't need to connect to the master that's actual writing
WAL. (Ex. Standby2 in Cascade Replication: Master - Standby1 - Standby2)
I'm worried how I should clear these problems.
Regards.
