That's a pretty clear indication of data corruption. pg_upgrade isn't going to be able to work with a corrupted source database, so you'll have to do something to clear that before you can get anywhere. There's some advice about dealing with that here: https://wiki.postgresql.org/wiki/Corruption but in general the news is not going to be good. regards, tom lane
