Hi,
I noticed after upgrading to 3.2.0-08812-gc2bc3a3 that Postgres-9.1 server fails to start with error:
FATAL: could not create shared memory segment: Function not implemented
DETAIL: Failed system call was shmget(key=5432001, size=30523392, 03600).
After some googling, I thought it was a SYSV shared memory sizing issue but manually changing kernel.shmmax and kernel.shmall had no effect.
The problem has been introduced between 3.2.0-08694-g53999bf and 3.2.0-08812-gc2bc3a3.
Let me know if you need any more information. Bisecting is *very* slow on this machine!

If you run strace on it, does it fail with ENOSYS? This might be
related to an issue Peter just fixed.

Yes, it almost certainly is. Fixed in rc1.
