Re: System V IPC on Windows

That makes sense, thanx.

Another individual was having problems adjusting the shared_memory
settings higher than 1.2GB on a 8GB 64bit machine running Vista.
Whenever he would adjust higher than that, the postgresql service
wouldn't start throwing some kind of error. In linux, one would simple
adjust the SHMMAX settings. If there's no such setting in Windows, then
the problem must lie somewhere else.

On a side, the docs could be a little more clear on this.
(http://www.postgresql.org/docs/8.2/static/kernel-resources.html)
The only reference to Windows says "(For the Windows port, PostgreSQL
provides its own replacement implementation of these facilities)".

Cheers,
Kevin
