Jak vypsat vlastní typy pomocí Postgres information_schema

Pro referenci zde je SQL z \dT (pgAdmin používá stejný nebo podobný)

SELECT      n.nspname as schema, t.typname as type 
FROM        pg_type t 
LEFT JOIN   pg_catalog.pg_namespace n ON n.oid = t.typnamespace 
WHERE       (t.typrelid = 0 OR (SELECT c.relkind = 'c' FROM pg_catalog.pg_class c WHERE c.oid = t.typrelid)) 
AND     NOT EXISTS(SELECT 1 FROM pg_catalog.pg_type el WHERE el.oid = t.typelem AND el.typarray = t.oid)
AND     n.nspname NOT IN ('pg_catalog', 'information_schema');
