I have a postgres-postgis dB with a geometry:point field: if I insert the
values directly
INSERT INTO points(coordinates) VALUES (ST_GeomFromText('POINT(10.809003
54.097834)',4326));
no issue, but if I use this sequence (Python)
*->import data in a dataframe: data contains lat and long columns;*
*-> trasform the lon,lat column in a shapely.geometry.point;*
*->create a geodataframe (gdf)*
*->connect to dB with psycopg2 and sqlalchemy*
gdf.to_sql('<mytable>, conn,if_exists='append
',index=False,schema=<myschema>)
I got this error:
--------------------------------------------------------------------------ProgrammingError
Traceback (most recent call

Any hints?
