Thank you for comments, did I mention the system is a beast? # cat /proc/sys/kernel/shmmax 68719476736 It can not be the resource limit, it has to be something else. I assume this version of postgres is incompatible with RedHat ES 5. Changing to a newer version of postgres is not an option for now. It would take too much time to rewrite the application to work with the changes introduced in the lastest realeses.
