I just tested your new test_fsync as included in the 8.2rc1, and it's
working perfectly for me now on Linux. All the O_SYNC writes using
O_DIRECT are reporting realistic timings. I'm happy that this code is
working as it should and appreciate the quick response. I still think the
wal_sync_method documentation deserves an update noting that O_DIRECT is
used when available with the sync write methods.
