Comment(by dustymugs):

 Yes.  The answer coming out is exactly the same answer as that from
 gdalwarp.  I've attached a TIFF matching the raster in your example.  If
 you warp that image with gdalwarp

 {{{
 gdalwarp -t_srs EPSG:3978 test4269.tif test3978.tif
 }}}

 The output matches that of ST_Transform.
