get Postgres UDT value with JOOQ - postgresql

Question

In Postgres, i created a UDT as follows
CREATE TYPE MY_TYPE AS ENUM ('FAILED', 'SUCCESS');
and in postgres cli, i can retrieve the UDT value back like
\dT+ MY_TYPE
which lists the details of the UDT, including its enum values under the 'Elements' column
EDIT: added result of "\dT+" command
postgres=# \dT+ status_type
List of data types
Schema | Name | Internal name | Size | Elements | Owner | Access privileges | Description
--------+-------------+---------------+------+----------+----------+-------------------+-------------
public | status_type | status_type | 4 | WAITING +| Postgres | |
| | | | STARTED +| | |
| | | | PAUSED +| | |
| | | | SUCCESS +| | |
| | | | FAILED | | |
Now, I am using JOOQ in a spring project, and want to get that UDT's value using JOOQ. Can anyone help me on how to get that done?
NOTE: I know that JOOQ generates the ENUM types when generating classes, But is that the only way to get the information i need?
Thanks!

I'm assuming you want to get a listing of all the enum literals from the database, dynamically. The SQL query that the jOOQ code generator uses for this similar to this:
SELECT n.nspname, t.typname, e.enumlabel, e.enumsortorder
FROM pg_enum e
JOIN pg_type t ON e.enumtypid = t.oid
JOIN pg_namespace n ON t.typnamespace = n.oid
ORDER BY n.nspname, t.typname, e.enumsortorder
Now, just run this query using jOOQ like any other query to get something like this (from the Sakila database):
nspname |typname |enumlabel |enumsortorder |
--------|------------|----------|--------------|
public |mpaa_rating |G |1 |
public |mpaa_rating |PG |2 |
public |mpaa_rating |PG-13 |3 |
public |mpaa_rating |R |4 |
public |mpaa_rating |NC-17 |5 |
