No, it's a filesystem bug that this particular filesystem doesn't
support a perfectly reasonable combination of options, and doesn't
even fail gracefully as it could easily do. But assigning blame
doesn't help much.
I wouldnt call it a reasonable combination - promising fs-level data-
journaling (data=journal) and O_DIRECT are not really compatible with each
other...
OK, but how is an application supposed to know that data journaling is
set. Postgres doesn't even look at the FS type, let alone the mount
options. From the app's POV it's perfectly reasonable. If the OS is
going to provide the API, it should expect people to use it.
