-`matrix_metrics_exposure_enabled`|Set this to `true` to **enable metrics exposure for all services** on `https://matrix.DOMAIN/metrics/*`. If you think this is too much, refer to the helpful (but nonexhaustive) list of individual `matrix_SERVICE_metrics_proxying_enabled` variables below for exposing metrics on a per-service basis.
+`matrix_metrics_exposure_enabled`|Set this to `true` to **enable metrics exposure for all services** on `https://matrix.DOMAIN/metrics/*`. If you think this is too much, refer to the helpful (but nonexhaustive) list of individual `matrix_SERVICE_metrics_proxying_enabled` (or similar) variables below for exposing metrics on a per-service basis.
 `matrix_metrics_exposure_http_basic_auth_enabled`|Set this to `true` to protect all `https://matrix.DOMAIN/metrics/*` endpoints with [Basic Authentication](https://en.wikipedia.org/wiki/Basic_access_authentication) (see the other variables below for supplying the actual credentials). When enabled, all endpoints beneath `/metrics` will be protected with the same credentials
 `matrix_metrics_exposure_http_basic_auth_users`|Set this to the Basic Authentication credentials (raw `htpasswd` file content) used to protect `/metrics/*`. This htpasswd-file needs to be generated with the `htpasswd` tool and can include multiple username/password pairs.
 `matrix_synapse_metrics_enabled`|Set this to `true` to make Synapse expose metrics (locally, on the container network)
 `matrix_synapse_metrics_proxying_enabled`|Set this to `true` to expose Synapse's metrics on `https://matrix.DOMAIN/metrics/synapse/main-process` and `https://matrix.DOMAIN/metrics/synapse/worker/TYPE-ID`. Read [below](#collecting-synapse-worker-metrics-to-an-external-prometheus-server) if you're running a Synapse worker setup (`matrix_synapse_workers_enabled: true`). To password-protect the metrics, see `matrix_metrics_exposure_http_basic_auth_users` above.

-`matrix_prometheus_services_proxy_connect_prometheus_node_exporter_metrics_proxying_enabled`|Set this to `true` to expose the node (general system stats) metrics on `https://matrix.DOMAIN/metrics/node-exporter`.

 `prometheus_postgres_exporter_enabled`|Set this to `true` to enable the [Postgres exporter](configuring-playbook-prometheus-postgres.md) (locally, on the container network)
+`prometheus_postgres_exporter_container_labels_traefik_enabled`|Set this to `true` to expose the [Postgres exporter](configuring-playbook-prometheus-postgres.md) metrics on `https://matrix.DOMAIN/metrics/postgres-exporter`. To password-protect the metrics, see `matrix_metrics_exposure_http_basic_auth_users` above.
 `matrix_prometheus_nginxlog_exporter_enabled`|Set this to `true` to enable the [NGINX Log exporter](configuring-playbook-prometheus-nginxlog.md) (locally, on the container network)

To password-protect the metrics, see `matrix_metrics_exposure_http_basic_auth_users` above.
 `matrix_bridge_hookshot_metrics_enabled`|Set this to `true` to make [Hookshot](configuring-playbook-bridge-hookshot.md) expose metrics (locally, on the container network)
 `matrix_bridge_hookshot_metrics_proxying_enabled`|Set this to `true` to expose the [Hookshot](configuring-playbook-bridge-hookshot.md) metrics on `https://matrix.DOMAIN/metrics/hookshot`. To password-protect the metrics, see `matrix_metrics_exposure_http_basic_auth_users` above.
 `matrix_SERVICE_metrics_proxying_enabled`|Various other services/roles may provide similar `_metrics_enabled` and `_metrics_proxying_enabled` variables for exposing their metrics. Refer to each role for details. To password-protect the metrics, see `matrix_metrics_exposure_http_basic_auth_users` above or `matrix_SERVICE_container_labels_metrics_middleware_basic_auth_enabled`/`matrix_SERVICE_container_labels_metrics_middleware_basic_auth_users` variables provided by each role.
