O_DIRECT supported on this platform for open_datasync and open_sync.
Compare open_sync with different write sizes: (This is designed to compare the cost of writing 16kB in different write
open_sync sizes.)
Test if fsync on non-write file descriptor is honored: (If the times are similar, fsync() can sync data written on a different
descriptor.) ư> .A%s%s /usr/lib/postgresql/9.6/bin /../ %s: out of memory
