I figured as much.  That's why I'm implementing the cache, rather than
downloading the same data over and over again.

Planet does not include history, correct?

That was one of the questions in my original post.  What's the
nicest/friendliest way to download all the history for a particular US

things like materialized views to make accessing the database
efficient without making the core schema itself a mess.
