7/7/12 8:24:23.117 PM com.heroku.postgres-service: FATAL: could not create shared memory segment: Invalid argument
7/7/12 8:24:23.117 PM com.heroku.postgres-service: DETAIL: Failed system call was shmget(key=5432001, size=14499840, 03600).
7/7/12 8:24:23.117 PM com.heroku.postgres-service: HINT: This error usually means that PostgreSQL's request for a shared memory segment exceeded your kernel's SHMMAX parameter. You can either reduce the request size or reconfigure the kernel with larger SHMMAX. To reduce the request size (currently 14499840 bytes), reduce PostgreSQL's shared memory usage, perhaps by reducing shared_buffers or max_connections.
7/7/12 8:24:23.117 PM com.heroku.postgres-service: 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.
7/7/12 8:24:23.117 PM com.heroku.postgres-service: The PostgreSQL documentation contains more information about shared memory configuration.
