quite a common problem... see http://www.postgresql.org/docs/8.3/static/kernel-resources.html

obvious question: what's in /proc/sys/kernel/shmmax ?

Thanks for your help. /proc/sys/kernel/shmmax was just a bit below the shared memory requested by Postgres.

Increasing the kernel's maximum shared memory did the job by adding a line to /etc/sysctl.conf and thereby inreasing it to 100MB:
kernel.shmmax = 104857600
