   @bchapuis Great job on the pull request! I will look at your new one for nested groups.
   
   I would be really interested in making an example to go from Overture data on S3 to serving MVT to a Maputnik frontend.
   
   I think this would mean:
   
   1 Fix the code to be able to use a S3 url directly. E.g. s3a://overturemaps-us-west-2/release/2024-05-16-beta.0/theme=admins/type=*/*
   2. Use the GeoParquetDataTable to write Overture data into Postgresql using a ProjectionTransformer to go from EPSG:4326 to EPSG:3857
   3. Create a geospatial index for the geometry column
   4. Create a materialised view to group the columns into a TAGS jsonb field and maybe simplifications for different zoom levels
   5. Make a simple style.json and tileset.json to serve the data
   
   What do you think?
