It shouldn't crash.  I suspect you tried this, got

ERROR:  stack depth limit exceeded
HINT:  Increase the configuration parameter "max_stack_depth".

and blindly followed the HINT without any regard for whether the value
you picked was actually safe on your platform.  If you make
max_stack_depth bigger than what the kernel allows, you will indeed
get a crash; but that's not a bug it's pilot error.

More recent PG versions try to limit max_stack_depth to a safe value,
but 8.0 just believes what you tell it.
