1. I like copying and pasting the "postgres" line during development.
That's not a reason to keep it, necessarily.
2. If you're saying, most people shouldn't run postgres directly, then
most people also shouldn't run initdb directly. This message will
mainly be seen either by developers or testers or tutorial users or
do-it-yourselfers. In which case knowing the functionality of the
postgres program is valid.
3. It's not clear that pg_ctl is necessarily the best way to start the
server. With things like systemd, launchd, supervisord that like to
manage the daemons directly, using postgres directly might be the
preferable choice.
