Interesting. After reading this I went back to the docs and found what I
haven't found before:

"Analogous to ON DELETE there is also ON UPDATE which is invoked when a
primary key is changed (updated). The possible actions are the same."

I was under the impression that cascades only applied to deletes.

Something new to chew on.

Thanks!
