There was a spike in data recovery business here after people started
migrating to ext4. New filesystems are no fun to roll out; some bugs
will only get shaken out when brave early adopters deploy them.

And there's even more radical changes in btrfs, since it wasn't starting
with a fairly robust filesystem as a base. And putting my tin foil hat
on, I don't feel real happy about assuming *the* solution for this issue
in PostgreSQL is the possibility of a filesystem coming one day when
that work is being steered by engineers who work at Oracle.
