We should probably stay with 9.2 until we have a way to default to sysv on FreeBSD releases that do not have their mmap performance fixed. To my knowledge there has not been a proposed patch for any release or head/CURRENT yet.

 AFAIK, the performance problem is a general FreeBSD kernel issue, not
 really something mmap specific.
 
 There may be some performance differences between Postgres 9.3 and
 Postgres 9.2 on FreeBSD but it's nothing compared to the gap between
 FreeBSD and Linux.
