Value range of IPC semaphores

[Nguyen Tam Chinh]

Hello,

I'm tuning some IPC semaphores parameters in 6.1-STABLE for a busy 
PostGreSQL server (8.1.4). I still now can not find the value range 
(exactly the maximum value) and its dependencies on other system wide 
parameters of these parameters: kern.ipc.semmni, kern.ipc.semmns, 
kern.ipc.shmseg and kern.ipc.shmmni.
The server is a dual Xeon 3.6 with 8Gb of RAM.

Please advice.

PS. The last change for me is going to read the source code, but I hope 
that someone in this mailing-list would tell me where to read or would 
give a good answer.
