MaVerick apparently implements something Pick-like on top of
PostgreSQL... <http://www.maverick-dbms.org/articles/article1.html>
And IBM Universe and UniData *do* make this into SQL...

And it's also worth considering that we have array types that support
something Like MV, although that's quite a separate debate.
Or perhaps not; let me suggest the thought that it would be more
worthwhile to examine the notion of adding MV SQL keywords to PostgreSQL
than it would be to try adding a batch scheduler...
