RE: http://archives.postgresql.org/pgsql-hackers/2002-05/msg00030.php There are a few variations, but it seems I am making the same assumptions as Lincln Yeoh. So, you are saying that when a search for a specific tuple happens, you have to hit every version of the tuple, no matter what? It isn't a linked list? I guess I don't understand. Why does it have to visit all of them? If ordering them from newest tom oldest, and then take the first transaction ID that it smaller then current transaction id, doesn't that work? ---------------------------(end of broadcast)--------------------------- TIP 6: Have you searched our list archives? http://archives.postgresql.org
