You can always cheat and copy what psql does when you tell it to list all
user types with extended output (\dt+):
postgres=# SET log_min_duration_statement = 0;
SET
postgres=# SET client_min_messages TO LOG;
LOG: duration: 0.137 ms statement: SET client_min_messages TO LOG;
SET
postgres=# \dT+
LOG: duration: 2.901 ms statement: SELECT n.nspname as "Schema",
pg_catalog.format_type(t.oid, NULL) AS "Name",
t.typname AS "Internal name",
CASE WHEN t.typrelid != 0
THEN CAST('tuple' AS pg_catalog.text)
WHEN t.typlen < 0
THEN CAST('var' AS pg_catalog.text)
ELSE CAST(t.typlen AS pg_catalog.text)
END AS "Size",
pg_catalog.array_to_string(
ARRAY(
SELECT e.enumlabel
FROM pg_catalog.pg_enum e
WHERE e.enumtypid = t.oid
ORDER BY e.enumsortorder
),
E'\n'
) AS "Elements",
pg_catalog.pg_get_userbyid(t.typowner) AS "Owner",
CASE WHEN pg_catalog.cardinality(t.typacl) = 0 THEN '(none)' ELSE
pg_catalog.array_to_string(t.typacl, E'\n') END AS "Access privileges",
pg_catalog.obj_description(t.oid, 'pg_type') as "Description"
FROM pg_catalog.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 <> 'pg_catalog'
AND n.nspname <> 'information_schema'
AND pg_catalog.pg_type_is_visible(t.oid)
ORDER BY 1, 2;
List of data types
Schema | Name | Internal name | Size | Elements | Owner | Access
privileges | Description
