A data point: I was recently confused when I observed the "startup" process
running for a bit after restarting the instance (because connections were being
rejected) I concluded that the shutdown was unclean, and started to blame the
PGDG RPM's initscript [0].
Actually, the shutdown was clean, and the "startup" process was just slow doing
$somethingelse (I imagine this will be less confusing in pg15 - 9ce346eabf).
[0] I believe this is configured such that systemd could kill -9 the postmaster
(but that's not what happened in this case).

If you rename "startup", I think "recovery" would be a bad choice, since it
seems to imply that recovery/wal replay was necessary.
