This is an example implementing the AccountsDb plugin for PostgreSQL database.
Please see the `src/accountsdb_plugin_postgres.rs` for the format of the plugin's configuration file.
To create the schema objects for the database, please use `scripts/create_schema.sql`.
`scripts/drop_schema.sql` can be used to tear down the schema objects.
