Hmm ... that is a really good point, except that you are not counting
the "lob." or "plob." part, which we previously saw is part of the
relation name not the schema name.  Counting that part, it's already
overlimit, which seems to be proof that Andrey isn't using UTF8 but
some single-byte encoding.

Anyway, that would only explain the issue if pg_upgrade were somehow
changing the database encoding, which surely we'd have heard complaints
about already?  Or maybe this has something to do with pg_upgrade's
client-side encoding rather than the server encoding...
