[postgis-users] GDAL Version

[Bborie Park]

Yes.  PostGIS raster uses GDAL for the loader (for the numerous source
raster formats), warping API, one of the two possible polygonization
methods (ST_DumpAsPolygons) and the rasterization function.

The main reason for GDAL 1.9 is correct output of pixel values from
ST_DumpAsPolygons which consumes GDAL's polygonization methods.
