Therefore for now what we've not reached the consensus is what message
should be logged at PM_STARTUP. I'm thinking it's better to log
"the database system is starting up" in that case because of the reasons
that I explained upthread.

I understand your point now, and I agree, that makes sense.

Please note that PM_STARTUP mode is very very short-lived.  It only
starts happening when postmaster launches the startup process, and
before the startup process begins WAL replay (as changed by
sigusr1_handler in postmaster.c).  Once WAL replay begins, the PM status
changes to PM_RECOVERY.

True if archive recovery or standby server. But during crash recovery
postmaster sits in PM_STARTUP mode. So I guess that we still see
the log messages for PM_STARTUP lots of times.
