36.62. view_column_usage
  The view
  
   view_column_usage
  
  identifies all
   columns that are used in the query expression of a view (the
  
   SELECT
  
  statement that defines the view).  A
   column is only included if the table that contains the column is
   owned by a currently enabled role.
 
Note
Columns of system tables are not included. This should be fixed sometime.
