Comment(by dustymugs):

 Ah.  I think I may be onto something...

 {{{

 That -1 vs 1 Y-scale will cause issues.  I'm going to have to chew on this
 since it will involve poking at raster2pgsql (at it specifies the generic
 geotransform).

 Just for kicks, can you up date the Y-scale of the raster and then rerun
 ST_SummaryStats()?

 {{{
 UPDATE armory_outdb SET rast = ST_SetScale(rast, 1, 1)
 }}}
