fsync -> fdatasync in backend/storage/file/fd.c

I don't remember if it has been mentioned.

Anyhow, I think that it would be nice to change fsync'es into
fdatasync'es (of course as an autoconf-igurable option). I don't think
it's necessary to update all file's metadata each time a file is
flushed.

I dunno where it's implemented. But it's for sure implemented in Linux.
