Hi,
Using PgAdmin connecting via user: root to the database and running the select works.
Adding same SQL into the queries.yaml confimap and patch/deleting the deployment and recreating the deployment....the metrics is missing.
Note: same user is used inside the deployment.
only metric which appears (out of the 3 queries): pg_postmaster
metric missing: pg_index_usage_*
