The view data_type_privileges identifies all
data type descriptors that the current user has access to, by way
of being the owner of the described object or having some privilege
for it. A data type descriptor is generated whenever a data type
is used in the definition of a table column, a domain, or a
function (as parameter or return type) and stores some information
about how the data type is used in that instance (for example, the
declared maximum length, if applicable). Each data type
descriptor is assigned an arbitrary identifier that is unique
among the data type descriptor identifiers assigned for one object
(table, domain, function). This view is probably not useful for
applications, but it is used to define some other views in the
information schema.
