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...
