You can tell Loader which tables to load with the constraint and exclude
(undocumented in 0.22) args.

You can "use" the standard loader class, and then load a custom module which
redefines whatever routines you want to override in the original. It may be
bad manners, but c'est la vie; it works. I don't like how CDBI::Loader
discovers relationships, so I redefined &_relationships in
CDBI::Loader::mysql::Grok (on CPAN). Ideally, I'd like to patch the
original, but in the meantime, there's nothing wrong with the results.
