I have been playing with the WKT Raster plugin. I have installed the WKT Raster experimental binaries in PostGIS successfully and followed the instructions in the read me to the letter.
When i am in QGIS I use the WKT Raster plugin to "Load Raster to PostGIS" everything seems to run fine there but once completed I get this error below.
Even though I get this error the table shows up in PostgreSQL and I can load it into QGIS but it does appear empty/blank. I checked in PostgreSQL and the table is there and it has values in it. Also the error message says "DbError: relation '' already exists", but its the first time I have ever created a table with that name in the DB.
Any ideas?
Thanks Ando
Answer
I'm a WKTRaster developer (now is called PostGIS Raster). I strongly recommend you to use the last PostGIS Raster version, integrated in PostGIS. And the last GDAL version (1.8.0). The GDAL driver (used for communication with QGIS) in GDAL versions previous to 1.8.0 was buggy and unstable.
