Yeah, I believe ARD does have an embedded postgres instance. You might
be running into Apple's ridiculously low system-wide SHMMAX setting;
it's only big enough to let one postgres run at a time, unless you
hobble performance by reducing shared_buffers etc well below default.
See our manual for how to increase SHMMAX on OS X --- it's trickier
than it ought to be :-(
