It seems to me that there would be a whopping lot of value to the exercise of figuring out some way of "layering" MVD on top of a relational database, even if only to provide something sufficiently analytical to cope with the perpetual claims of: "MultiValued Databases are Vastly, Spectacularly, the Bestest Kind of Database ever imagined in the universe! No, really they are!" It might not be necessary to go all the way to fully layering such a thing atop PostgreSQL, although it would be a nice riposte to be able to respond with: "Been there, done that.
