PostgreSQL 9.3 benchmarks

[B. Estrade]

Nice work.

Looks like FreeBSD 10 is not fully utilizing all the cores or there are
some serious migration/contention issues going on. Trying FreeBSD 9.x might
help in pointing to any 10.x (still a young distro) issues.  You may also
want to try some artificial benchmarks that are used specifically for
testing SMP scaling - like the NASA NPBs -
