Super interesting compiling pg, I assume, with same as the zfs block size! It was always on our todo to try, but never got around to it. If possible, what block size did you end up with? Have you tried zfs direct io in 2.3.x, if so, could you share any findings? Thanks for sharing - and cool website!

I use Postgres with 32K BLKSZ.
I am actually using default 128K zfs recordsize, in a mixed workload, I found overall performance nicer than matching at 32K, and compression is way better.
