I agree that the open flag is more nearly O_DSYNC than O_SYNC.
ISTM Windows' idea of fsync is quite different from Unix's and therefore
we should name the wal_sync_method that invokes it something different
than fsync. "write_through" or some such? We already have precedent
that not all wal_sync_method values are available on all platforms.
I'm not taking a position on which the default should be ...
