You can either reduce the request size or reconfigure the kernel with larger SHMMAX. To reduce the request size (currently 38207488 bytes), reduce PostgreSQL's shared_buffers parameter (currently 4096) and/or its max_connections parameter (currently 103). If the request size is already small, it's possible that it is less than your kernel's SHMMIN parameter, in which case raising the request size or reconfiguring SHMMIN is called for. The PostgreSQL documentation contains more information about shared memory configuration. Checking the kernel settings: sudo sysctl -a | grep -i shm kernel.shmmax = 33554432 kernel.shmall = 2097152 kernel.shmmni = 4096 The shared_buffers setting defaults to 32MB. I changed this down to 25MB to test and then the server would start right up.
