Re: Adjusting Shared Memory with sysctl.conf not working?

Hi Doug,

I have a very similar configuration to yours, but I was able to install
PostgreSQL successfully through dumb luck; that is, I simply ignored the
advice about the shared memory just to see what would happen. The
installation apparently is smart enough to fix one's environment
automatically now, and I received this nice message telling me to re-boot
and re-run the installer. I did that and everything works just fine. You
may simply want to delete /etc/sysctl.conf and try again.

Good Luck,
Dennis Clark
