This is the tables.sql file out of the CVS. It is useful for me to have here for reference.
-- SQL to create the initial tables for the Wikipedia database.
-- This is read and executed by the install script; you should
-- never have to run it by itself.

-- Indexes should be defined here; please import the rest from indexes.sql.
