writing data using gdal ogr2ogr?

Hi, I tried to write geospatial data to the PostGIS enabled database (from geojson) using gdal ogr2ogr: ``` ogr2ogr -f "PostgreSQL" PG:"host=host port=5432 dbname=postgres user=postgres password=password" campings.geojson -nln public.campings ``` But it gives the following message: ``` Warning 1: User lacks super user privilege to be able to create event trigger ogr_system_tables_event_trigger_for_metadata ```` Probably something with the PostGIS metadata tables. In tutorials I see that an extra step is used (writing sql file using ogr2ogr, and import the sql file). I got that working, but would like to avoid this extra step. So the question is: how can we write directly to the database using ogr2ogr (without converting to sql file)?
