That may or may not be true. What other OSes have ZFS someone could
try to duplicate your results and then test fixes for them? I run
various linux flavors, but would be more than willing to repurpose a
test server for pgsql testing freebsd. Got an 8 disk HW RAID machine
due in in a month I could test on for a few days. It appears the only
way to run it under linux (my primary OS) is with fuse. But I'm
willing to try it there too.
