Rewriting the schema – a more radical approach

In some cases, it may make sense to rewrite the database schema and provide an old view for unchanged queries using views, triggers, rules, and functions.

One such case occurs when refactoring the database, and you would want old queries to keep running while changes are made.

Another case is an external application that is unusable with the provided schema, but can be made to perform OK with a different distribution of data between tables.
