Postgres Raster image display

[Ryan Ollerenshaw]

How can i use a Postgres database to display raster images with
Mapserver?  There are lots of examples on display features this way
and using a gdaltindex to create a shapefile but i cant find any that
talk about using a database to store raster images.  Here is what i am
currently trying:

LAYER
  NAME "stereo_simp"
  TYPE RASTER
  PROCESSING "SCALE=AUTO" #rescale 16-bit image to 8-bit
  STATUS on
  CONNECTION "host=localhost dbname=test user=postgres"
  CONNECTIONTYPE POSTGIS
  DATA "location FROM stereo"
  TILEINDEX "stereo" #the table name
  TILEITEM "location" #column that contains the path to the image
END

if i just try and display the image directly it works just fine:

LAYER
  NAME "stereo_simp"
  TYPE RASTER
  PROCESSING "SCALE=AUTO" #rescale 16-bit to 8-bit
  STATUS on
  DATA "/hiview/products/data/20070929_000600_14euA_171_16_gdal.tif"
END

Thank you for your time,
