Обсуждение: pgsql: Add wal_sync_method=fdatasync for Windows.
Add wal_sync_method=fdatasync for Windows. Windows 10 gained support for flushing NTFS files with fdatasync() semantics. The main advantage over open_datasync (in Windows API terms FILE_FLAG_WRITE_THROUGH) is that the latter does not flush SATA drive caches. The default setting is not changed, so users have to opt in to this.
