I did a bit of googleing and came up with the following papers: http://www.eecs.berkeley.edu/IPRO/Summary/97abstracts/marcel.1.html but the only references I saw to implementation were in something called amdb. If he did code it for postgresql, even an old version, having that code/info available (if even as a link from the TODO) might be enough to inspire someone to implement it in the current sources.
