Hi Andreas,

The SQL file has been generated. Could you load it into Postgres?

Anyway, I strongly recommend you to use the new version of PostGIS
Raster (WKTRaster was the old name). Now PostGIS Raster is part of
PostGIS, and is packed with it (not official version yet, you need to
check it out from repository). The old version you're using is no
longer maintained
