I tried the settings you gave and they worked (with some caveats). After I recompiled the FreeBSD kernel with the options: options SYSVSHM options SYSVMSG options SYSVSEM options SHMMAXPGS=131072 options SEMMNI=128 options SEMMNS=512 options SEMUME=100 options SEMMNU=256 I rebooted and attempted to start postgresql and it failed again. I then ran sysctl -a to verify that the settings were correct. They were not. Regardless of what's configured in the kernel conf file, the default values were loaded. I had to edit my /etc/sysctl.conf and /boot/loader.conf file to get it to work. Which makes me wonder why the settings are even in the kernel conf file.... but that's not relevant to this list. But the values you provided did allow me to start up postgresql with max_connections set up to 479 (480 is too high and causes error).
