Thanks for the review! The present is not checking the existence of specification of -S. The use case when replication slot is not specified. Because it does fsync, it isn't an original intention. remote_write is set in synchronous_commit. To call attention to the user, append following documents. "If you want to report the flush position to the server, should use -S option." Regards, -- Furuya Osamu
