Why would you guess?  "SHOW archive_command" will tell you, without
question, at any time.  I don't see the point of placing such a message
in the postmaster log --- in normal circumstances the postmaster will
still be running long after its starting messages have been discarded
due to log rotation.

Also, the current implementation allows you to stop and start archiving
on-the-fly, so a start-time message would be an unreliable guide to what
the postmaster is actually doing at the moment.
