If initdb fails on this, then either you don't have shared memory
support in your kernel at all, or the limits are so small that Postgres
can't usefully run under them. Putting in a config file wouldn't help.
What platform are you on exactly, and what exactly is the failure
message? Also, what PG version are we talking about?
