The test dataset is here: http://www.naturalearthdata.com/downloads/10m-raster-data/10m-cross-blend-hypso/ Imported with this command: {{{ raster2pgsql -C -I -s 4326 -Y -t '256x256' HYP_LR.tif hyp_lr }}} It looks like a bug for ST_Rescale to not maintain topology as the manual says that the tile extent could be slightly modified to accomodate for subpixel scaling. I hadn't tested with older versions" defect reopened medium PostGIS Fund Me raster master
