The logic in the patch is ok, but I'd use a different error message,
one that just mentions that you can only upgrade a primary node:
The source cluster was shut down while in recovery mode, but
pg_upgrade expected a primary node.
The error referring to the target node should be similar, although I
can't think of how to phrase it without saying "how on earth did you
get a standby for the target! RTFM!" :-D
