I just tested these two commits.
https://git.postgresql.org/cgit/postgresql.git/commit/?id=3da13a6257bc08b1d402c83feb2a35450f988365
https://git.postgresql.org/cgit/postgresql.git/commit/?id=b0e96f311985bceba79825214f8e43f65afa653a

it will alter table and add not null constraint internally (equivalent
to `alter table test alter id set not null`).
