I'm starting my first PostGIS project, and in various books and tutorials I've seen the geometry column labelled either 'geom' or 'the_geom'. Is one more conventional than the other?
Furthermore, is there a good reason to use 'geom'/'the_geom' instead of a more descriptive name for the geometry column? (E.g. 'centre_point' for the central point of a feature.) We don't label conventional db columns 'the_int' or 'the_string', so why label geometry columns this way?
