[postgis-users] Questions about the right uploading of raster data

I have one "rid" column and one "rast" column but only with one row, 1 - 0. So i guess the upload wasn't correct, right? I tried the command you said but no error messages. I use OSGeo4W console and i have installed through this the GDAL 1.8.1-1. Sometimes i get a message saying: gdalinfo.exe - System Error "The program can't start because MSVCR90.dll is missing from your computer. Try reinstalling the program to fix this problem". I reinstalled osgeo4w but nothing changed. Maybe that's the problem? I should start installing dlls manually? Any other way to install gdal 1.8 without OSGeo4W in Windows 7 exists?

You should have one "rid" column and one "rast" column. And since you loaded using the -k option you should have many rows in the "katrina" table.
If this is not what you get I would suggest to replace the raster2pgsql.py -o option with a pipe like this:
raster2pgsql.py -r /path/to/katrina.tif -t katrina -l 1 -k 64x64 -s 4326 -I -M > Katrina.sql
to see more error message.

Before trying to display in QGIS make sure the raster was loaded properly...
