Hello! I'm messing with behavior of geometry index operators and can't understand one thing. Operators &< (overleft) and &> (overright) are defined in Postgres as comutative to each other. However their definitions doesn't seem to commute
a &< b is the same as a->xmax <= b->xmax and b &> a is the same as b->xmin >= a->xmin Right parts of this seem to be completely unrelated. Do I misunderstand somthing or it is a bug in the definition? -- Vladimir Kikhtenko _______________________________________________ postgis-users mailing list [email protected] http://lists.osgeo.org/cgi-bin/mailman/listinfo/postgis-users
