Brent,
Does this help:

What version of gdal do you have installed. You might need the mode=2
argument on the DATA statement.

Hi,
I'm looking to (eventually) manage several hundred raster layers in Postgis.
I have prototyped a single layer using a worldclim file, and can open
the Postgis raster table in QGIS (using db manager) and display it as
expected with pseudocolour. It is a single band layer, with pixel values
in the -36 to 30 range (avg temperatures).
I have set up a mapfile to serve this as a WMS. I can connect to the
service with QGIS, see the layer listed and add it to the canvas. The
legend shows the three colours I have set as classes for the layer, but
the layer does not appear on the canvas (or if it does it is invisible).
The mapserver log suggests (to me anyway) that it is working OK.
I have added a global land shapefile, also served as WMS to the same
mapfile to give some context, which opens and displays OK as a WMS layer
in QGIS.
The mapfile, along with the mapserver log entry, are at
https://pastebin.com/2jjGFYaW
If anyone can help me sort out why I'm not seeing any data in QGIS from
the Postgis raster WMS layer, I'd appreciate it!
Thanks
