@nilason I would personally prefer to have the postgis port follow the latest upstream version and, if needed, in the future to split off something and add a version number to it. That's how it's done for many/most packages. Any reason why not to do that here?

Very good point, I absolutely agree, I will replace the postgis with the currentpostgis3 (which I will deprecate for now in case of future need).
