Hi Micha, thanks for the tip! I managed to do it with the following command from FWTools shell:
ogr2ogr -update -append -f "PostgreSQL" PG:"host=localhost user=postgres dbname=db password=xxx" my_gps_points.gpx waypoints -sql "SELECT name AS gps_nimi, time AS gps_aika FROM waypoints" -t_srs EPSG:3067 -nln my_table_name I selected the fields I wanted, and cast them to different field names in my db table. I only wanted waypoints, and also did a coordinate transformation from wgs84 -> ETRS-TM35FIN. Very handy, once you get the syntax right. Now the only manual thing left is to change the input gpx file name every time, if all other parameters stay constant.
