Yeah, it wasn't clear before, but it looks like there are specific
rows that there's something wrong with.

I would like to know the ctid's of the -1 rows in the copied table,
along with the ctid's of the rows they share magic_ids with, and
the ctid's of the rows with those same magic_ids in the original.
I'm wondering whether the affected rows are physically clustered ...
