view data types

Hi All,

Is there a simple way to determine the data type(s) of columns in a view?

IOW what I would really like to be able to do is

SELECT data_type
   FROM magic_table
  WHERE view_name = 'my_view'
    AND column_name = 'my_column';

data_type
---------
      int4

I have been snooping around in the pg tables but I haven't found the
correct one yet.
