## Database configuration

There variables are needed for the database authentication.

| Variables            | Default value    | Description                |
|----------------------|------------------|----------------------------|
| DB\_HOST              |                  | Postgresql server address. |
| DB\_PORT              |                  | Postgresql server port.    |

If your Postgresql cluster use read-only replicas, you can configure the API
with these variables to distribute the read-only requests through all of them.
Each of these variable is a comma separated list. If each replica have a different
configuration, the order in each list matter: the first element `REPLICA_DB_HOSTS`
will use the first port in `REPLICA_DB_PORTS` and so on.
