Logsender risk of transmitting incomplete tranlog records due to fync timing

n a hotstandby system, the Stone tracks the completed transaction log records, and when a record has been written, the logsender reads from the on-disk transaction logs and transmits the tranlog records to the logreceiver.

When the write is complete, however, there is a risk that the disk fsync was not finished, in which case the record that is read from disk by the logsender and sent to the logreceiver may be incomplete.
