You are talking about 244142d, right? I see this code bit:
+ if (strcmp(p, "shut down\n") != 0)
+ {
+ if (cluster == &old_cluster)
+ pg_fatal("The source cluster was not shut down cleanly.\n");
+ else
+ pg_fatal("The target cluster was not shut down cleanly.\n");
+ }

This seems incorrect for me in the case of standbys, as pg_controldata
reports in this case "shut down in recovery", and one can run pg_upgrade
on a standby as well, no?
