This is a nice feature if it is safe to turn off full_page_writes.
When is it safe to do that? On which platform?
I am not aware of any released software that allows full_page_writes
to be safely disabled. Perhaps something has been released recently
that allows this? I think we have substantial documentation about
safety of other settings, so we should carefully document things here
also.
