              Isn't WAL essentially sequential writes during normal

            Only if you have some sort of non-volatile
              intermediary, or are willing to risk your data integrity.
               Otherwise, the fsync nature trumps the sequential nature.
            

    That would be a "no" on the data integrity :-)
