Add documentation for geography field types (GeographyPoint, GeographyLineString, GeographyPolygon, GeographyGeometryCollection), spatial filter operators (intersects, dwithin, distance, contains, within), GIST index support, and a guide for upgrading existing projects to use PostGIS.
Rename 04-upgrade-to-postgis.md to 05-upgrade-to-postgis.md to avoid a collision with the existing 04-archive/ directory in the upgrading section.
