[postgis-users] Import Raster with 3 bands to PostgreSQL

[Mauricio de Paulo]

Sorry but I didn't understand what you're trying to do. Could you 
elaborate more?
Were the 3 bands stored in a single file when you used raster2pgsql? If 
that's the case, you should be able to see your data in qgis.
If not, the 3 separate files had nothing to tell that they were separate 
bands of the same imagery and were probably merged as a mosaic in 
raster2pgsql. I've never tried that with overlapping data but certainly 
qgis isn't ready to read special scenarios like this one.
