Update does not work when setting generated column to default

[angelamayxie]

The following query works in Postgres but errors out in Doltgres

postgres=# create table t1 (i int primary key, j int generated always as (i + 10) stored);
CREATE TABLE

postgres=# insert into t1 (i, j) values (1, default);
INSERT 0 1
postgres=# select * from t1;
 i | j  
---+----
 1 | 11
(1 row)

postgres=# update t1 set j = default where i = 1;
UPDATE 1

Doltgres error: ERROR: UPDATE: non-Doltgres type found in source: () (SQLSTATE XX000)
