In the following log file the presence of "exit code 1" after performing a "pg_ctl stop -m smart" shutdown is bugging me. I take it most people would just ignore it as noise but a clean install from source, startup, and shutdown would ideally not result in a non-zero exit code being sent to the log. But I've decided to stop trying to track it down on my own and at least mention it here. It seems like f669c09989 probably introduced the behavior, and I can see how "restarting" is generally a good thing, but we are not going to restart the launcher during a clean shutdown and the exit code isn't being done conditionally.
