I've stumbled into a problem with some raster too. It seems like a gdal bug. But I could get it to work with the image available at: <a href="http://trac.osgeo.org/gdal/wiki/frmts_wtkraster.html">http://trac.osgeo.org/gdal/wiki/frmts_wtkraster.html</a><br>
Looks like gdal is still improving the non-regular raster reading and performance.<br>Well.. then I'm going to release a new version with the same lib as pgmanager to make it easier to merge.<br>Hum... preview through pgmanager... I didn't think about it. Sounds good. I'm going to review the code and see what i can do to make it happen.<br>

</div>Yes, I'm on Debian.<br>
In fact:<br>
<div class="im">Warning: QSqlDatabase: QPSQL driver not loaded<br>
</div>Installing libqt4-sql-psql does the trick.<br>
However, I have the server on another machine, and the pg versions do not match, so I<br>
get Warning: This version of PostgreSQL is not supported and may not work.<br>
And in fact it does not work well: the raster is loaded, but I only get NULLs and 0<br>
instead of true values. Unsure, however, if the raster was loaded correctly in the db.<br>
<br>
On the machine where I have the db, I get instead (but this coudl be to mismatching<br>
pg versions, as I have both 8.4 and 9.0 istalled):<br>
Error:<br>
GDAL Error 4: `PG: dbname=nove host=localhost user=nove password=***** port=5433<br>

and is not recognised as a supported dataset name.<br>
<br>

</div>I think it would be good not to add further cryptodependencies.<br>

</div>I think the best would be to integrate with both "Add PostGIS vector" for loading and<br>
with PostGIS manager for previewing and loading.<br>
<br>
All the best, and thanks a lot!<br>
