Perfomance degradation 9.3 (vs 9.2) for FreeBSD

Hi!

I see performance degradation with PostgreSQL 9.3 vs 9.2 on FreeBSD, and I'm wondering who to poke to mitigate the
problem.In reference to this thread [1], who where the FreeBSD people that Francois mentioned? If mmap needs to perform
wellin the kernel, I'd like to know of someone with FreeBSD kernel knowledge who is interested in working with mmap
perfocmance.If mmap is indeed the cuplrit, I've just tested 9.2.8 vs 9.3.4, I nevere isolated the mmap patch, although
Ibelieve Francois did just that with similar results. 

Enclosed is a report from a simple pgbench check.
