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."
