Question

I tried to install PostgreSQL 9.1.2 for Mac OS X 10.6 and it asked me to edit the sysctl.conf file inside the /etc/ directory, so it could use more of the shared memory PostgreSQL was asking for.

I went ahead and edited the file, saved it, rebooted and then on the login screen I was asked to login as safe boot for some reason, I logged in and internet did not seem to work and the dock menu was laggy.

So it was pretty obvious this was happening because of the sysctl.conf file that I edited before the reboot, so I went back into the /etc directory and deleted the sysctl.conf file thinking it would auto-create a new sysctl.conf file with the default settings but that wasn’t the case even after a reboot.

So now I’m pretty much left without a sysctl.conf file, I read the Mac Developer documentation for this file and it didn’t say much. I know I probably shouldn’t be messing with files that I don’t have a clue about but I really wanted to get PostgreSQL working for my local Ruby on Rails development.

Anything on this topic would be helpful.

Mine contains the following:

kern.sysv.shmmax=134217728
kern.sysv.shmmin=1
kern.sysv.shmmni=256
kern.sysv.shmseg=64
kern.sysv.shmall=32768

I have Lion myself but I don’t think there was anything else in it when I was using Snow Leopard.
