Add PostGIS support #1
Description
Coming from https://github.com/marians/dwd-weather/issues/8, we want to add PostGIS support in the future to unlock querying the station list using GIS operations as we are already doing to the station list from luftdaten.info with Luftdatenpumpe, see also LDI data plane v2.
The outcome of that will converge into one or more Grafana Dashboards @wetterfrosch is currently working on over at weather.hiveeyes.org and we will be happy to share all results with the community.
