Apparently some of the earlier versions did not permit changing this parameter without recompiling the kernel. It seems to have been changed in the more recent versions, though:

A note from that last URL is that shmall*4096=shmmax.
And yes, trying to manually run an rc script is a bad idea.

Remembering that this was a problem for starting two postmasters at the same time on OS X, I increased the shmmax value to 500 megabytes (I had seen something say raising it to half the available ram would be fine), but when I rebooted my machine neither 8.0 or 7.4.5 would start.
So I lowered it to 256 megabytes, thinking there might be an upper limit on that kind of stuff. When I rebooted my machine, 7.4.5 starts fine, but 8.0 still will not start alongside it.
I don't particularly need both postmasters running at the same time, but I would like to figure out the solution to this problem.
(By the way, in the course of this I attempted to manually run /etc/rc ... there were humorous results and my computer didn't really like it: http://www.visualdistortion.org/misc/dont_do_this.png)
