Debian and Ubuntu have a sysctl.conf that is processed at boot time, but it
does not contain anything related to shm* by default.

Suse has a sysctl.conf, but it is not processed at boot by default. You have
to activate a special boot service in the runlevel system to make it actually
run at boot. (Try explaining that to a PostgreSQL user.) There is nothing
related to shm* in the default configuration.
