How did the DragonFlyBSD team performance benchmark [1] against Postgres version 9.3 when the latest stable release is 9.2.1 and no development release of 9.3 is available?

Postgres 9.3-devel: http://www.postgresql.org/docs/devel/static/install-getsourc...

That these benchmarks were done with 9.3-devel was important; part of what triggered this work was PostGres moving to a different way of mapping it's shared memory segment (mmap vs shm), the benchmarks were initially done to see how much that hurt.
