Comment (by pramsey):

 You're right, there's not any explicit documentation on the meaning of &&
 in the geography context, mostly because it's damnable hard to explain.

 With respect to ST_Intersection(), note that it's a bad hack on top of
 transforms to planar (have a look at the SQL definition for that
 function), so the fact that it doesn't work over the dateline doesn't
 entirely surprise me.

 If your conclusion is that "geography implementation in postgis isn't very
 complete/good" I have no strong argument with you. It's... better that not
 having one. But only somewhat.
