Almost sure this is a GDAL problem but it is avoiding me to display,
load or export raster from postgis. :-(
Im using gdal 1.9.0 though.

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"

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.
