I believe that error is a false positive. The postgres_exporter server should not be able to start if it's unable to connect to the PostgreSQL database (see the lower line). This can happen while things the system is starting up: the exporter is trying to connect to a database that is not fully available yet. That is the typical error when it fails to connected. As it runs SELECT now(); to check the connection, you can see the successful connection at that point in the log line.

Anyway, this is not an issue. That said, I'll add some documentation in one of the troubleshooting sections.
