[postgis-users] Raster displaced when loading or make a new one

[Jose Carlos Martinez]

Hi,
Im getting a problem with raster in PostGIS 2.0, r9200.
  POSTGIS="2.0.0alpha6SVN" GEOS="3.3.2-CAPI-1.7.2" PROJ="Rel. 4.7.1, 23 
September 2009" GDAL="GDAL 1.9.0, released 2011/12/29" LIBXML="2.7.8" 
USE_STATS

I have loaded a raster file successfully. The layer is dem1 and the 
raster column is rast.
The  when I try to make any new raster from this one, even just a copy 
of it:

alter table dem1 add column rast1 raster;
update dem1 set rast1 = rast;
--UPDATE 132
select addrasterconstraints ('dem1','rast1');

I got the new raster 'rast1' displaced.
Dont know what im doing wrong. QGIS and GDAL_translate to png show the 
same problem (maybe its no a postgis problem but a gdal problem?):
I uploaded a pdf with the images [1].

PD: Im having similar problems when I try to load a tif raster to PostGIS.

The constrains are the same in both:
ra1=# \d dem1

  Column |  Type   |                     Modifiers
--------+---------+----------------------------------------------------
  rid    | integer | not null default nextval('dem1_rid_seq'::regclass)
  rast   | raster  |
  rast1  | raster  |
