That's right . The excluded.* pseudo-table isn't exactly the same
thing as the target table -- it is a tuple that has the same "shape",
that represents what the implementation tried (and failed) to insert
into the table. I have to imagine that Alex wants to reference that,
because that's the standard idiomatic approach with ON CONFLICT. And
because the only alternative interpretation is that Alex intends to
update those columns using their current values (not new values),
which won't really change anything -- that seems unlikely to have been
the intent.
