postgresql jsonb类型中的两个值是否相同？

-- 示例数据
CREATE TABLE data (id SERIAL, json_data JSONB);

INSERT INTO data (json_data) VALUES ('{"name": "John", "age": 25}');
INSERT INTO data (json_data) VALUES ('["apple", "banana"]');
INSERT INTO data (json_data) VALUES ('"hello"');

-- 使用相等运算符进行比较
SELECT json_data = '{"name": "John", "age": 25}' AS is_equal FROM data;
-- 输出: true

SELECT json_data = '["banana", "apple"]' AS is_equal FROM data;
-- 输出: true

SELECT json_data = '"hello"' AS is_equal FROM data;
-- 输出: true

-- 使用不等运算符进行比较
SELECT json_data <> '{"name": "John", "age": 25}' AS is_not_equal FROM data;
-- 输出: false

SELECT json_data <> '["banana", "apple"]' AS is_not_equal FROM data;
-- 输出: false

SELECT json_data <> '"hello"' AS is_not_equal FROM data;
-- 输出: false
