It would be amazingly helpful to get object_ids for post_ids, so that we can better analyse the performance of an object across multiple posts.
An object is an asset ,like a photo or a video file, and a post can include objects in it. An object can be posted multiple times (i.e. you share a video that exists on a page multiple times to the timeline).
Presumably this would best go in the POST_HISTORY table or in a new OBJECT_HISTORY table which joins on post_id?
