Huh! Not what I expected:

postgres@salmo:~$ pg_upgrade -c -b /usr/lib64/postgresql/11/bin/ -B
/usr/lib64/postgresql/12/bin/ -d /var/lib/pgsql/11/data -D
/var/lib/pgsql/12/data/

(All on one line; wrapped by alpine.)

Well, of course they're from different major versions, that's why I'm
running pg_upgrade. What did I do incorrectly?
