PgPersister
The PgPersister interface represents a Persister that lets you save and load Store data to and from a PostgreSQL database, via the pg module.
You should use the createPgPersister function to create a PgPersister object.
It is a minor extension to the Persister interface and simply provides an extra getPg method for accessing a reference to the database connection the Store is being persisted to.
