Comments on computed column functions are not present in the resulting GraphQL schema
```sql
CREATE FUNCTION person_full_name(person person) RETURNS text AS $$
  SELECT person.given_name || ' ' || person.family_name
$$ LANGUAGE sql STABLE;

COMMENT ON FUNCTION person_full_name IS 'The full name of this person.';  -- 👈
```

The `Person.fullName` field does not have the "The full name of this person." comment.
