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 shared buffers cached
Mem: 7867 1860 6007 0 5 595
-/+ buffers/cache: 1258 6609
