Florencia,
I have not tried to do this and I'm not sure it is even possible, but
you might have some luck using a GDAL connection to pull your postgres
raster data into mapserver. If you get this to work post a "how to" to
the list.
Thanks,

Florencia,
As far as I know, Mapserver only works with vectorial data on PostGIS.
So having a kind of BLOB (bytea)
column doesn't work.
I guess you will have to had those TIF files as a file to be able to
load it using a RASTER layer.

Hi,
I have my data rasters (tif files) into my PostGIS database such as file.
Any file into database is in "bytea" format.
I want to show this raster layer from PostGIS with mapserver. My "Raster
Table" structure and my .map code are:
TABLE rasters (
id serial NOT NULL,
nombre character varying(100),
archivo_bytea bytea,
mime character varying(100),
size double precision
)
LAYER
NAME 'Raster'
TYPE RASTER
CONNECTIONTYPE postgis
CONNECTION "user=postgres password=... dbname=... host=..."
DATA "bytea FROM rasters"
STATUS OFF
OFFSITE 0 0 0
TRANSPARENCY 100
END
Thanks a lot.
Regards.
Florencia
