2014-06-18 13:37:15 EDT FATAL: could not map anonymous shared memory: Cannot allocate memory
2014-06-18 13:37:15 EDT HINT: This error usually means that PostgreSQL's request for a shared memory segment exceeded available memory or swap space. To reduce the request size (currently 8826445824 bytes), reduce PostgreSQL's shared memory usage, perhaps by reducing shared_buffers or max_connections.
