PromQL is barely a language. For availability, the query would be as simple as the series name and it would return everything. Also, there's an adapter so that Prometheus writes to PostgreSQL. However, Prometheus is not a tool that specializes in reporting availability to people who live in Excel. Prometheus scrapes metric from a lot of systems in a standard format, and enables you to see what's happening and write alerts to fix things when they break, without requiring complex frameworks. Reporting availability to people is just a small, tiny thing that Prometheus is able to do.
