I did a default configure and did not change anything in the .conf
file. It requests 10444800 bytes. But even if I drop max_connections
down to 10, it still won't start. Yes, I can modify SHMMAX for the
operating system to make it work but I'm trying to understand why I
need to do this when it was not necessary under 7.3 or an earlier 7.4
development build (pre beta 1). I was hoping it is a bug, because I
think it hurts the adoption of Postgresql if I have to worry about a
lot of low level OS settings just to setup a simple database.

Best,

John DeSoi, Ph.D.
