Descriptions

args: rastschema, rasttable, rastcolumn, srid=true, scale_x=true, scale_y=true, blocksize_x=true, blocksize_y=true, same_alignment=true, regular_blocking=false, num_bands=true, pixel_types=true, nodata_values=true, out_db=true, extent=true - Drops PostGIS raster constraints that refer to a raster table column. Useful if you need to reload data or update your raster column data.
