Good point ... but what if the corruption is subtle enough that the
automatic tests don't notice it? It could be that only "SELECT * FROM ..."
actually dumps core. This is an acute problem for tests that are
generic enough to be implemented in just one or a few places --- for
example, the tests I just added have no idea whether they are looking
at a heap or index page, much less what kind of index page.

We have "DESTROY ALL PAGES", it's called DROP TABLE. The other doesn't
appeal to me either, because it doesn't say exactly which N pages you're
willing to lose.
