3 The view <code class="literal">data_type_privileges</code> identifies all
4 data type descriptors that the current user has access to, by way
5 of being the owner of the described object or having some privilege
6 for it. A data type descriptor is generated whenever a data type
7 is used in the definition of a table column, a domain, or a
8 function (as parameter or return type) and stores some information
9 about how the data type is used in that instance (for example, the
10 declared maximum length, if applicable). Each data type
11 descriptor is assigned an arbitrary identifier that is unique
12 among the data type descriptor identifiers assigned for one object
13 (table, domain, function). This view is probably not useful for
14 applications, but it is used to define some other views in the
