geopandas.GeoDataFrame.to_postgis using SQLAlchemy sessionmaker as connection

[cath222ou]

Hi everyone,

I'm wondering if it's possible to use SQLAlchemy sessionmaker as a connection for geopandas.GeoDataFrame.to_postgis?
I'd like to use to_postgis to validate whether the data in my gpkg respects my database schema without writing data to the database. So I'd like to use the sessionmaker's rollback function even if no exception has been caught.

Thanks !
