well, try something like...

     kernel.shmmax = 4294967295
     kernel.shmall = 268435456

at the end of /etc/sysctl.conf, then execute `sysctl -p` and try to start
postgres again.

(it really doesn't matter if you set those kernel limits too large, they
have no negative impact, they are simply quota, the max allowed.   The
only reason to restrict them is on a shared system with hostile/malicious
users like students who might mess with grabbing excessive memory and
causing a denial of service. )
