This error does *not* mean that you have run out of disk space. It occurs either if all available shared memory IDs have been taken, in which case you need to raise the SHMMNI parameter in your kernel, or because the system's overall limit for shared memory has been reached. If you cannot increase the shared memory limit, reduce PostgreSQL's shared memory request (currently @1@ bytes), perhaps by reducing shared_buffers or max_connections.The PostgreSQL documentation contains more information about shared memory configuration.
