Comment:

 I was thinking of a possible solution to this issue...

 1. before doing anything to the set of import rasters, see if the set are
 aligned

 2. if set of input rasters aligned, overviews are guaranteed to be aligned

 As it looks like raster2pgsql may need to move away from using VRTs for
 overviews, this would be an appropriate change to make at the same time.
