If it dies even at max_connections 10, that is a *lower* setting than we
ever supported before (the pre-7.4 default was 32, and you need 20 or
more to run the parallel regression test). I suspect that you actually
don't have SysV semaphores enabled at all on that machine. There would
be no point in trying any smaller values.
