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,
reallythey 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
riposteto be able to respond with:
 
 "Been there, done that.  Of _COURSE_ PostgreSQL supports MultiValue."
