And indeed, while upgrading to FreeBSD 4.10, I configured
SysV shared memory according to:

    http://developer.postgresql.org/docs/postgres/kernel-resources.html

which boils down to adding the following options or modify them
in the kernel config to:

    options         SYSVSHM
    options         SHMMAXPGS=3D4096
    options         SHMSEG=3D256

    options         SYSVSEM
    options         SEMMNI=3D256
    options         SEMMNS=3D512
    options         SEMMNU=3D256
    options         SEMMAP=3D256

Now I can run PostgreSQL and raidutil simultaneously.
