问是否可以将枚举类型从一个模式复制到另一个模式？

EN

create schema api;
create schema private;
create role web_anon nologin;
-- web_anon doesn't have usage on the private schema
grant usage on schema api to web_anon;

-- create type and domain
create type private.grade as enum('a','b','c','d','e');
create domain api.grade as private.grade;

-- The function uses the domain api.grade instead of private.grade
create or replace function
  api.get_grade(g api.grade) returns text as $$
begin
  return (select g);
end;
$$ language plpgsql;

-- This change will reflect on the domain
alter type private.grade add value 'f';
