 As described here: http://lists.osgeo.org/pipermail/postgis-
 devel/2014-July/024337.html

 The ST_Rescale function breaks coverage topology introducing gaps between
 a tile and another whereas ST_Resize does not.

 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
