Ah, that is unfortunate. If you have access to the data explorer plugin I think something like this should replicate the /deleted/posts list for a particular user (with post_id thrown in for good measure):
-- [params]
-- user_id :user_id
SELECT p.created_at AS reltime$time,
id AS post_id,
id
FROM posts p
WHERE p.user_id = :user_id
AND p.deleted_at IS NOT NULL
ORDER BY p.created_at DESC
