Yeah, I feel so and it is what I wondered about recently when I saw
some complete error messages. Is that because of the length of the
subject?

Yes... I don't find a written reason excluding pg_upgrade in both the
commit 9a374b77fb and or the thread [1]. But I guess that we decided
that we first provide the facility in the best style ignoring the
current impletent in pg_upgrade then let pg_upgrade use it. So I
think it should emerge in the next cycle? I'll give it a shot if no
one is willing to do that for now. (I believe it is straightforward..)
