Ah, thanks for the clarification. Having seen how much garbage accumulates in that field it never occurred to me that someone would think to grab and use it *directly*.
Yes, the UUID idea sounds good. That said, the short-link implementation seems fraught with conflict anytime posts get merged from multiple databases. Does WordPress' import handle tracking those and fixing them up with 301 redirects? Also, seems like using post_ids is a very fragile solution?
