The implications of such a thing really are so far-reaching that it could not be isolated in a nice little layered API.

For better or for worse, I think we're married to MVCC. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 6: Have you searched our list archives? http://archives.postgresql.org
