Hmm. Maybe we should have the plist file set KeepAlive to false not true?
This would mean you'd need manual action to restart a failed postmaster,
but that probably comes with the territory --- I do not see how we'd
teach launchd the difference between a "failed" postmaster and a manually
shut down one.

I think the normal way to stop/restart a launchd service is to use
"launchctl unload/load" ... we'd need to see how that interacts with
using pg_ctl. Some documentation might be needed in any case.
