Andriy,

Not really. sysctl.conf is basically empty. Maybe these lines are of interest:

# PostgreSQL
# (see http://people.freebsd.org/~seanc/postgresql/postgresql-kern-autotune.sh)
# tuned to 8 GB for shared mem
kern.ipc.shmall=2097152
kern.ipc.shmmax=8589934592

But postgres is idle on this machine, and ipcs -a shows for shared memory

Shared Memory:
T           ID          KEY MODE        OWNER    GROUP    CREATOR  CGROUP      
  NATTCH        SEGSZ         CPID         LPID ATIME    DTIME    CTIME
