+## Dumping
+Assuming we are working with a postgresql statefulset, our namespace is named `miniflux` and our master pod is named `db-postgresql-0`, trying to
+dump a database named `miniflux`:
+{{< highlight sh >}}
+export POSTGRES_PASSWORD=$(kubectl get secret --namespace miniflux db-postgresql -o jsonpath="{.data.postgresql-password}" | base64 --decode)
+kubectl run db-postgresql-client --rm --tty -i --restart='Never' --namespace miniflux --image docker.io/bitnami/postgresql:11.8.0-debian-10-r19 --env="PGPASSWORD=$POSTGRES_PASSWORD" --command -- pg_dump --host db-postgresql -U postgres -d miniflux > miniflux.sql-2020062501

+## Restoring

+Assuming we are working with a postgresql statefulset, our namespace is named `miniflux` and our master pod is named `db-postgresql-0`, trying to
