How to write from pandas Dataframe to PostgreSQL with a geometry type

Hello,
In my python receipt, I would like to write in my PostreSQL database (with PostGis extension) data with a geometry type. Therefore, I declared a schema and created my table with this specific schema
schema = [{"name": 'id', "type": 'int'}, {"name": 'value', "type": 'string'}, {"name": 'the_geom', "type": 'geometry'}]
test_schema = dataiku.Dataset("test_schema")
test_schema.write_schema(schema, dropAndCreate=True)
with test_schema.get_writer() as writer:
writer.write_dataframe(df_test)
However there's no way "Dataiku" recognizes any geometry type I tried. Is it possible to have the list of types that Dataiku can handle?

Hi,
At the moment, it's unfortunately not possible to directly write Postgis types directly from Python. What we would recommend is to write the WKT as a string column, and then use a SQL Script recipe to copy it into a geometry column.
Adding real support for Postgis is on our roadmap, but we do not yet have an ETA for this. -
Ok, thank you for your anwser

Hello Clément,
Have you any news on that topic? I have the same issue with visual recipes. Do we still have to add a SQL scripts to our Workflow?
Thanks in advance
