Is it possible to load a shape file to a postGIS database by replacing the content of the table with the new content of the shape file WITHOUT DROPING the table? I want to do this using ogr2ogr. In the past I have used shp2pgsql, which gives you the option of four flags ((-drop|-append|-create|-prepare) but none of these options actually maintains the table and deletes the data. Is there something like this in ogr2ogr?
