This is covered in more depth in the Admin documentation, chapter 3.5. An
online version can be found at:

http://postgresql.readysetnet.com/devel-corner/docs/admin/kernel-resources.html

Specifically, it says:

"FreeBSD, OpenBSD

The options SYSVSHM and SYSVSEM need to be enabled when the kernel is
compiled. (They are by default.) The maximum size of shared memory is
determined
by the option SHMMAXPGS (in pages). The following shows an example of how to
set the various parameters:

     options         SYSVSHM
     options         SHMMAXPGS=4096
     options         SHMSEG=256

     options         SYSVSEM
     options         SEMMNI=256
     options         SEMMNS=512
     options         SEMMNU=256
     options         SEMMAP=256
