| * | Properly mark initRectBox() as taking 'void' args | Bruce Momjian | 2016-04-23 |

| * | Suppress uninitialized-variable warnings. | Tom Lane | 2016-03-30 |
| | | | | | | | My compiler doesn't like the lack of initialization of "flag", and I think it's right: if there were zero keys we'd have an undefined result. The AND of zero items is TRUE, so initialize to TRUE. | ||
| * | Introduce SP-GiST operator class over box. | Teodor Sigaev | 2016-03-30 |
| Patch implements quad-tree over boxes, naive approach of 2D quad tree will not work for any non-point objects because splitting space on node is not efficient. The idea of pathc is treating 2D boxes as 4D points, so, object will not overlap (in 4D space). The performance tests reveal that this technique especially beneficial with too much overlapping objects, so called "spaghetti data".
