another project for techdocs?

There was recently a request for a sample
database for postgresql on pgsql-general.

The point of having one or more of these
is to show off features.

Illustra had the video store database.
Informix had something similar as did
Sybase and Ingres. Oracle apparently
has several examples of databases
to show off a variety of market focussed
features. And there is the ubiquitous
department-division-employees variations.

These are usually small applications,
ideally including a front end which
require basic rdbms features (shows
solidity) and a few of the whiz bang
features (shows off). The techniques
in the app can be mined by new
developers, too.

The applications should be re-usable in
tutorials or classes.

Does anyone have things like this built
already? I have a couple of very small apps,
but they are generally tied to reporting.

Or is anyone interested in creating
a new one? Or packaging up an exisiting one?
I'd be happy to collaborate on one
but I don't have the bandwidth to code
up a new one.
