Hi,

Even more interestingly, when I wanted to make the change permanent in
/etc/sysctl.conf, I read:

$ tail -3 /etc/sysctl.conf
# necessary for postgresql 9.1 to even start
kernel.shmmax= 5922496

Implying that I already ran into this problem, but at that time, 5922496
was the correct amount of memory to get it started. Is this plausible or
did I make a mistake when saving that value? Did the SHM requirements of
postgresql increase recently within 9.1?

Best regards,
Michael
