Hi,
I'm using postgresql 9.1 as my database server on a linux server that has 8 GB

After I changed the shared_buffers parameter to 2GB, I get the following error
when I try to start postgres:
FATAL: could not create shared memory segment: Cannot allocate memoryDETAIL:
Failed system ca

SHMALL is measured in pages not bytes on Linux. I wonder if that value

Thank you for your answer. I think the value of shmall I have is very common
cause I've seen it many times in other servers.Do you think there maybe a link
between the request size of postgres and the swap size?
Here is the output of free -m
free -m total used free sh
