pg_catalog.has_type_privilege ( [ user name or oid, ] type text or oid, privilege text ) → boolean

Does user have privilege for data type? The only allowable privilege type is USAGE. When specifying a type by name rather than by OID, the allowed input is the same as for the regtype data type (see [Section 8.19](https://www.postgresql.org/docs/13/datatype-oid.html)).
