 the world2raster and raster2world plpgsql functions?

 Yep. It's actually performed by GDAL using the GDALApplyGeoTransform()
 function. GDAL is also used to calculate the inverse transform whenever
 the accessors are used to change the parameters of the affine transform
 (scale, skew, offset). In essence, the forward and reverse transforms are
 always pre-computed and ready for use.
