[postgis-users] Mapserver connection to Postgis Raster

I attached the sql.
I hope this could help to
find out whats happening.

This is what raster_columns has:

"r_table_catalog";"r_table_schema";"r_table_name";"r_column";"srid";"pixel_types";"out_db";"regular_blocking";"nodata_values";"scale_x";"scale_y";"blocksize_x";"blocksize_y";"extent"
"";"public";"HumedadDeExtincion";"rast";-1;"{64BF}";f;f;"";1000;-1000;;;""

thanks!
Virginia
