It's on the TODO list. It's just really hard to implement, especially

Postgres won't start up if the binaries don't match the data ... unless
someone has written a script which replaces the pg_control file :-(

I *really* don't want to see the graphic for Excited Elephant.
On the other hand, I think I already have a graphic for Grumpy Groupby ...
