I would have expected the relationship to work the other way, e.g.
create table City (
id integer primary key,
loc integer references CityLoc(id),
name text,
lat real,
long real,
class integer
);
create virtual table CityLoc using rtree (
id integer primary key,
lat_min real,
lat_max real,
long_min real,
long_max real
);
Or perhaps a junction table between the two, if it was possible to have a city
with more than one location, or if one location could be within two entities.
