It should just be
... AND aa.pr_date BETWEEN ?::date - ?::int AND ?::date
The type-name-at-the-front syntax is redundant with the cast, and
is only allowed for simple literal constants anyway. It worked for
you before because DBD-PG was replacing the ? marks with literal
strings, but it wasn't ever really "the right thing". See
