I set up synchronous replication with synchronous_transfer = all, and then I ran
pgbench -i and executed CHECKPOINT in the master. After that, when I executed
CHECKPOINT in the standby, it got stuck infinitely. I guess this was cased by
synchronous_transfer feature.

How does synchronous_transfer work with cascade replication? If it's set to all
in the "sender-side" standby, it can resolve the data page inconsistency between
two standbys?
