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.
