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. )
