PostgresModel class abstract

Postgres driver for Archery ORM.

This class provides static helpers for:

• registering model constructors for hydration (migrate<T>())
• creating tables/indexes for models
• executing CRUD operations against a PostgresDatabase connection

Models are discovered/registered by calling PostgresModel.migrate<T>() with a constructor (and optional column definitions).
