On a Linux system, if the total memory is 4G and the shmmax is set to 4G, I know it is bad, but how bad can it be? Just trying to understand the impact the "shmmax" parameter can have on Postgres and the entire system after Postgres comes up on this number.
What is the reasonable setting for shmmax on a 4G total machine?
Thanks a lot,
Jessica
