Shapefiles should work correctly with GDAL 1.2, postgis only with CVS version.

Yes.

Yes, I think that it is better to wait a while. At least until 
the patches are in GDAL. The raster support in QGIS is not perfect yet,
missing is support for floating point color tables because GDAL supports
only positive integers. We have already found the solution, but it is not 
yet implemented.


BTW 1: Am i right that there is no function which can read rules from
color table in GRASS, something like
G_get_color_rule( struct Colors *, int rule, 
                  CELL*, int*, int*, int*, 
                  CELL*, int*, int*, int*)
?

BTW 2: Color table is stored as double linked list, doesn't that make
G_get_raster_color too slow?
