Problem updating Postgres ENUM from DuckDB

I'm on DuckDB 1.4.1 experiencing difficulty updating a Postgres 17.6 ENUM field status:

CREATE TYPE mystatus_enum AS ENUM (
    'IN_STOCK', 'OUT_OF_STOCK', 'NOT_FOUND', 'NOT_A_PRODUCT'
);

CREATE TABLE mytable
(
    id INTEGER primary key,
    status mystatus_enum
);

All of the following give me:

Not implemented Error: Enums in Postgres must be named - unnamed enums are not supported. Use CREATE TYPE to create a named enum.

Making a similar update from within Postgres without DuckDB is not a problem.

Both for DuckDB sources:

update mypg.mytable set status=ddb.status where ddb.id=mypg.mytable.id;
update mypg.mytable set status=ddb.status::varchar where ddb.id=mypg.mytable.id;
update mypg.mytable set status=ddb.status::text where ddb.id=mypg.mytable.id;
update mypg.mytable set status=ddb.status::mypg.mystatus_enum where ddb.id=mypg.mytable.id;

and PG sources:

update mypg.mytable set status=mypg.mytable2.status where mypg.mytable2.id=mypg.mytable.id;

and as above but with PG sources.

I've also tried using an equivalent ENUM declared in DuckDB.

Any suggestions for how I can avoid this error? I'd like to avoid my last resort of switching the Postgres field from ENUM to VARCHAR as it is a very large and active table.
