Hi, sometimes ill get this error:
FATAL: could not create shared memory segment: Cannot allocate memory
DETAIL: Failed system call was shmget(key=2, size=4153344, 03600).
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 4153344 bytes), reduce PostgreSQL's
shared_buffers parameter (currently 400) and/or its max_connections
parameter (currently 20).
The PostgreSQL documentation contains more information about shared
memory configuration.
I was what exactly this shared memory space is used for and what size
is good to set it to. I need to be able to start up many backends
(postgres) without using the postmaster.
thanks!
