Can the extension use instead of pg_catalog.varchar (255), use varchar (255)

When selecting field data type, the suggested always fully qualify type name, like pg_catalog.varchar (255), which is unnecessary while we can use just varchar (255), for example:

CREATE TABLE doctors (
    first_name VARCHAR(255),
    last_name VARCHAR(255),
    specialization pg_catalog.varchar (255),
    acrive BOOL
);
