-This introduction will use PostgreSQL and Catalyst. Background information on using PostgreSQL with Catalyst can be found at L<Catalyst::Manual::Tutorial::10_Appendices>. This guide will assume that you have some understanding of Catalyst. Please go through the Catalyst tutorials first, if you have not yet done so.
