I'm afraid that is too easily confused with the target directory.
Generally, a tool processes data from input to output or from source to
target or something like that, whereas a log is more clearly something
separate from this main processing stream. The desired "output" of
pg_upgrade is the upgraded cluster, after all.
A wildcard idea is to put the log output into the target cluster.
