I think that Postgres doesn't allow the right-hand side of IN to be an $-parameter. Try something like this:
(defprepared addresses-by-ids "SELECT address FROM users WHERE id = ANY($1)" :column)
I think you'll still have to convert your list to a vector for cl-postgres to be able to put it in a parameter.
Many thanks.
