postgres-adapter authentication failed for 'postgres' db about prometheus-postgresql-adapter

Can you try setting the postgres user's password in pg_prometheus, and then putting that password in your config file in the appropriate place? The flag is -pg.password=. This tutorial also could be helpful, specifically the Spin up Pg_Prometheus step and the Docker configs.

Hello... When you spin up the Timescale Prometheus adapter as you passing in the password for the postgres user? It is unclear if you are not passing it in or simply removed it from the log entry you pasted in? from what I can see you may be failing in so far as you are not passing in a password? and rather than trust in your HBA add md5 let us know how it goes..
