* In 4.x, attach_post_key is only filled in when you upload an attachment but haven't submitted the post yet. Once the attachment is "saved" on a post, attach_post_key is blank.
* The system uses this to know which attachments can be deleted - when something is deleted, it will remove the rows from core_attachments_map and then delete all attachments which have no rows there *and* have no attach_post_key.
* In 3.x, attach_post_key was always filled in, even when an attachment had been saved. This meant that if you upgraded from 3.x, then deleted a post with an attachment on it, that attachment would never be deleted.
* This query wipes the attach_post_key for all attachments. It is done here so that the fix is retroactive. Thoeretically, anyome who started making an attachment before the upgrade here started may lose it, but this would be a rare occurance, and since
* we're performing an upgrade anyway, that's okay - it's better that old attachments are able to be deleted correctly.
*
* @return array If returns TRUE, upgrader will proceed to next step. If it returns any other value, it will set this as the value of the 'extra' GET parameter and rerun this step (useful for loops)
