Tom Lane	b90f8f20f0	Extend r-tree operator classes to handle Y-direction tests equivalent ... to the existing X-direction tests. An rtree class now includes 4 actual 2-D tests, 4 1-D X-direction tests, and 4 1-D Y-direction tests. This involved adding four new Y-direction test operators for each of box and polygon; I followed the PostGIS project's lead as to the names of these operators. NON BACKWARDS COMPATIBLE CHANGE: the poly_overleft (&<) and poly_overright (&>) operators now have semantics comparable to box_overleft and box_overright. This is necessary to make r-tree indexes work correctly on polygons. Also, I changed circle_left and circle_right to agree with box_left and box_right --- formerly they allowed the boundaries to touch. This isn't actually essential given the lack of any r-tree opclass for circles, but it seems best to sync all the definitions while we are at it.	21 years ago
Tom Lane	9a09248edd	Fix rtree and contrib/rtree_gist search behavior for the 1-D box and ... polygon operators (<<, &<, >>, &>). Per ideas originally put forward by andrew@supernews and later rediscovered by moi. This patch just fixes the existing opclasses, and does not add any new behavior as I proposed earlier; that can be sorted out later. In principle this could be back-patched, since it changes only search behavior and not system catalog entries nor rtree index contents. I'm not currently planning to do that, though, since I think it could use more testing.	21 years ago

Neil Conway	36ab600511	Cleanup of GiST extensions in contrib/: now that we always invoke GiST ... methods in a short-lived memory context, there is no need for GiST methods to do their own manual (and error-prone) memory management.	21 years ago

Teodor Sigaev	f2c064afcb	Cleanup vectors of GISTENTRY and eliminate problem with 64-bit strict-aligned ... boxes. Change interface to user-defined GiST support methods union and picksplit. Now instead of bytea struct it used special GistEntryVector structure.	22 years ago
