`prometheus_postgres_exporter_enabled`|Enable the postgres prometheus exporter. This sets up the docker container, connects it to the database and adds a 'job' to the prometheus config which tells prometheus about this new exporter. The default is 'false'
`prometheus_postgres_exporter_enabled`|Enable the Postgres Prometheus exporter. This sets up the docker container, connects it to the database and adds a 'job' to the Prometheus config which tells Prometheus about this new exporter. The default is 'false'
`prometheus_postgres_exporter_container_labels_traefik_enabled`|If set to `true`, exposes the Postgres exporter metrics on `https://matrix.example.com/metrics/postgres-exporter` for usage with an [external Prometheus server](#collecting-metrics-to-an-external-prometheus-server).
