#3045: &&& operator confuses dimensions

Reporter: strk | Owner: pramsey

Priority: medium | Milestone: PostGIS 2.0.7
Component: postgis | Version: 2.0.x

Comment(by strk):
So this seems to be an harder problem than it looked.
That is, if we really want to assume "missing" dimension are "infinite",
as suggested in
http://lists.osgeo.org/pipermail/postgis-devel/2015-February/024759.html
Then we need to "pad" the Z for a ZM point with an explicit infinite range
(-inf,+inf).
It sounds like something that would need to be done in
gserialized_datum_get_gidx_p which would then construct 4D boxes for 3DM
geometries (with a padding). That's unless we have ZM semantic in GIDX
which I think we don't ?
