PostgreSQL backend aggregator. One config knob for users:

```erlang
{repo, [
    {backend, kura_backend_postgres},
    {host, "localhost"},
    {database, "myapp"},
    {pool_size, 10}

The aggregator wires up:

- `pool_module` -> `kura_pool_pgo`
- `driver_module` -> `kura_driver_pgo`
- `dialect` -> `kura_dialect_pg`
- `capabilities` -> declared on `kura_pool_pgo`
