 Inheritance is not a general solution, and should be carefully considered.

 Keep in mind that postgreSQL inheritance is *structural* inheritance (I think of it as automatic `UNION`s which happen when I query the common fields; `NATURAL FULL JOIN`s play nicely into that).
 Advanced functionality is available with other `JOIN`s, Views, and `UPDATE` Rules.
