2013-04-19 22:35:50 MSK FATAL: could not create shared memory segment:
Invalid argument
2013-04-19 22:35:50 MSK DETAIL: Failed system call was shmget(key=5432001,
size=41263104, 03600).
2013-04-19 22:35:50 MSK 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 41263104 bytes), reduce
PostgreSQL's shared memory usage, perhaps by reducing shared_buffers or
max_connections.
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.
# sysctl kernel.shmmax
