PostGIS includes the raster_columns view to provide a high-level summary of all the raster columns found in the database. This view is similar to the geometry_columns and geography_columns views in function and form.
Let's run the following SQL query in the raster_columns view to see what information is available in the prism table:

The SQL query returns a record similar to the following:
If you look back at the gdalinfo output for one of the PRISM rasters, you'll see that ...
