It is short-sighted to load everything in the application, because at best utilizing the data in another context is going to involve a major (possibly painful) code refactor. You are more tightly coupling your data to your application stack, which isn't the best idea in my experience.

As an aside, Postgres supports multiple schemas for a given database, so it is trivial to support multiple versions of a single table, provide legacy support via views, etc.
