Notifying maintainers:
@Veence for port postgis2.

@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).

Update to mapnik 4.1.3 fails on Boost bug, addressed upstream with boostorg/gil@fcfce66. Dropping that update here as this PR is cascading too much.

This is now ready for review. I made the following changes:

• replaced postgis with current postgis3
• made postgis3 obsolete
• updated postgis2 to latest (EOL) version, and made the port deprecated
• updated (the dependant) osm2pgrouting to 3.0.0

The failing CI runner on macOS 26 is caused by missing dependency (mapnik) of a postgis dependent port (mod_tile). That should be fixed in a separate PR.
