Where's the problem?

test=# create table workflow(status_id character varying(10) collate "en_US");
CREATE TABLE
test=# \d workflow
                      Table "public.workflow"
  Column   |         Type          | Collation | Nullable | Default
-----------+-----------------------+-----------+----------+---------
 status_id | character varying(10) | en_US     |          |

test=# alter TABLE workflow alter status_id  TYPE character varying(10) COLLATE "C";
ALTER TABLE
test=# \d workflow
                      Table "public.workflow"
  Column   |         Type          | Collation | Nullable | Default
-----------+-----------------------+-----------+----------+---------
 status_id | character varying(10) | C         |          |
