I just did a fresh install of 7.4b5 on a fresh install of MacOS 10.3, and initdb
picked those same values for postgresql.conf. PostgreSQL started up the first
time successfully, but then refused to start again even after restarting the
computer until I reduced shared_buffers.
Now to figure out why sysctl -w kern.sysv.shmmax=<some_reasonable_value> doesn't
seem to work on 10.3...
