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.
