-- 1. 创建一个函数，用于在数据更新时自动修改 update_time 字段
CREATE OR REPLACE FUNCTION set_update_time()
RETURNS TRIGGER AS
$$
BEGIN
NEW.update_time = NOW();
RETURN NEW;

$$ LANGUAGE plpgsql;
-- 2. 创建表（使用 BOOLEAN 替代 SMALLINT for is_deleted）
CREATE TABLE t_user

id BIGSERIAL PRIMARY KEY,
username VARCHAR(60) NOT NULL UNIQUE,
password VARCHAR(60) NOT NULL,

-- WITH TIME ZONE 是更严谨的选择
update_time TIMESTAMP WITH TIME ZONE NOT NULL DEFAULT NOW(),

-- 3. 创建触发器，在每次 UPDATE 操作前调用函数
CREATE TRIGGER set_t_user_update_time

ON t_user
FOR EACH ROW
EXECUTE FUNCTION set_update_time();
-- 添加注释
COMMENT ON TABLE t_user IS '用户表（优化版）';
COMMENT ON COLUMN t_user.is_deleted IS '逻辑删除：FALSE：未删除 TRUE：已删除';
