Shared memory for RH Linux 7.1
In the past, I had to change the RedHat Linux kernel so that the
shared memory was set to something much higher than the default (which
I think was about 32 MBytes). It seems that this is no longer
necessary in RH 7.1 (kernel 2.4). Can someone confirm this?

One can:
echo 67108864 > /proc/sys/kernel/shmmax
To adjust limits
I think you still need to set your shared memory size, because my Redhat
7.1 gives me this:
[root@localhost kernel]# cat /proc/sys/kernel/shmmax
33554432
[root@localhost kernel]# uname -a
Linux localhost.localdomain 2.4.2-2 #1 Sun Apr 8 20:41:30 EDT 2001 i686
unknown
I think shared memory is set this low for compatability reasons, but I'm
not sure.

This is my first post here. I hope that I got
everything right...
This has already been possible for 2.2.x Kernels.
Check out the Postgresql admin documentation at
http://www.fr.postgresql.org/devel-corner/docs/admin/kernel-resources.html#SYSVIPC
Or did I get something wrong.
By the way. Is there a release date for PG 7.1.2?
