How to get a bounding box (in the form of a Polygon, or anything else where it's easy to extract the corner coordinates from) of a given Geography item? Something that would look like:
SELECT Boundary(geog) AS boundingBox FROM segments; Where geog is a MULTILINE geography.
Seems like a trivial question, but my experience so far is limited and I did not have any luck with the docs (http://www.postgis.org/documentation/manual-1.5/reference.html ) Tried ST_Boundary and Box2D but they do not work on geographies.
