Ответ на storing latitude and longitude  (mark <markkicks@gmail.com>)
Список pgsql-general
Hello,

Probably the simplest way is to use built-in point type and GiST index
over box(point, point). You will be able to make flat geometrical
calculations (e.g. distance with <-> operator) and retrieve data in
the box given with index support.

Regards,
 Ivan
