<p class="MsoNormal"><span style="font-family:"Arial",sans-serif;color:black">One of our users reported a difference in outputs after we upgraded from GDAL 2.2 to 3.2. Our tool is using gdal_translate to resample a raster from 5m to 10m and the outputs are
very different. <o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-family:"Arial",sans-serif;color:black">I'm ok with things changing between major versions, but when investigating, I found that the outputs also change depending on whether the input file has overviews. I was aware of
the issue with gdalwarp where overviews are used as a shortcut (<a href="http://erouault.blogspot.com/2014/10/warping-overviews-and-warped-overviews.html">http://erouault.blogspot.com/2014/10/warping-overviews-and-warped-overviews.html</a>), but haven't been
able to find anything similar in the docs or the code when it comes to gdal_translate.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-family:"Arial",sans-serif;color:black">Should overviews make a difference? Is there any way to disable this behaviour, so the resampling is always done using the input raster and not the overviews?
