There has never been any promise that you could load output from
pg_dump version X into server versions before X without manual
adjustments. Furthermore, this case doesn't even pose any particular
need for manual adjustments: you need only ignore the error.
I see no bug here.

FWIW, that typically happens when needed to break a circular dependency.
In this case, since the GROUP BY is obviously inadequate to make the
SELECT legal on its own, I speculate that the query is legal only because
invoice_invoice.id is a primary key, so that the rule has to be emitted
after that pkey constraint is created.
