This removes the magic allowing accessing configurable
variables directly from the config object. It is now required
that a specific configuration class is used (e.g. `config.foo`
must be replaced with `config.server.foo`).
Setting the value will help PostgreSQL free up memory by recycling
the connections in the connection pool.
