I find this article overstated. I ran some Postgres databases on ZFS for specialty needs for some time, mostly to take advantage of compression. It can be quite potent for this, though the amplification of CPU usage with a pathological access pattern can be a problem for some workloads. I did have some problems in early versions that seemed plausibly related to its contiguous memory needs, and later I saw a release quite drastically changed this (0.7), and indeed, it was stable from then on. I found it more cohesive to work with than other options available at the time, e.g. l2arc for caching. I didn't have need for pool dynamism, but I found it rather easy to use, though I also have experience with lvm and mdadm. That said, some of the source code I found more incomprehensible than average, and I'm fairly used to reading linux to answer certain questions. Maybe I just needed to study it longer.
