Nice work!  From initdb.sh:

    for nbuffers in 1000 900 800 700 600 500 400 300 200 100 50
    do
        TEST_OPT="$PGSQL_OPT -c shared_buffers=$nbuffers -c max_connections=5"
        if "$PGPATH"/postgres -boot -x0 $TEST_OPT template1 </dev/null >/dev/null 2>&1
        then
            break
        fi
    done
