tbox_index_consistent_leaf() bool tbox_index_consistent_leaf ( const TBox *  key, const TBox *  query, StrategyNumber  strategy  ) R-tree GiST index for temporal integers and temporal floats. These functions are based on those in the file gistproc.c. Leaf-level consistency for temporal numbers. Since temporal boxes do not distinguish between inclusive and exclusive bounds, it is necessary to generalize the tests, e.g., left : (box1->xmax < box2->xmin) => (box1->xmax <= box2->xmin) e.g., to take into account left([a,b],(b,c]) right : (box1->xmin > box2->xmax) => (box1->xmin >= box2->xmax) e.g., to take into account right((b,c],[a,b]) and similarly for before and after Parameters [in] key Element in the index [in] query Value being looked up in the index [in] strategy Operator of the operator class being applied Note This function is used for both GiST and SP-GiST indexes
