Is it possible to set shared memory settings on the fly in OS X like you
can in Linux e.g. sysctl -w kernel.shmmax=134217728
I have tried sysctl -w kern.sysv.shmmax=134217728 with no luck, i know you can edit /etc/sysctl.conf file.
But i would sooner set these settings as part of the postgresql control script.
