You're out of shared memory.  Did you shut down the old postmaster
before trying this?  The default shared memory size on OS X is not large
enough to run more than one postmaster at a time (unless you reduce
7.4's default shared_buffers and max_connections quite a bit).

If you didn't shut down the old postmaster cleanly (eg you did kill -9
or some such) then the old shared memory segment may still be hanging
around even though it's not in use.  OS X doesn't seem to have ipcs or
ipcrm, so there's no real easy way to check this, and no way to get rid
of such a segment except to reboot :-(.
        regards, tom lane
