[Qgis-user] Re: qgis/ Postgis raster plugin problem

[Mauricio de Paulo]

Hi Johannes,
At the moment GDAL's driver is not able to read irregularly tiled raster 
tables. This means that you cannot use the option to load many raster 
files in a single table. One workaround is to use VRT to build a single 
mosaic dataset before loading them to postgis.
Is that your problem?
All the best.
