I guess this is probably the cleanest/easiest.   Create my database and
write out the config in a BEGIN block -- or somehow otherwise delay loading

My other option could be to create my own instance of the Model object and
then swap it out in the MyApp->components hash.   The fact that my model is
dynamically generated at startup based on config adds a bit of complexity
to it -- but that can be handled.

BTW -- for tests where I need to build a database on-the-fly what I
currently do is set my "make test" config use dsn =3D> 'dbi:Pg' and then set
the PG* environment variables.   But, in this case what I'm doing is
swapping my Postgresql config in my configuration with one to use a SQLite
database in a temporary file just for a few tests.

Thanks for the ideas.
