在Python for Postgres中，jsonb数组的正确格式是什么？

[
    {"key1": "value1", "key2": "value2"},
    {"key3": "value3", "key4": "value4"}
]

import psycopg2
import json

# 连接到PostgreSQL数据库
conn = psycopg2.connect(database="your_database", user="your_user", password="your_password", host="your_host", port="your_port")

# 创建游标对象
cur = conn.cursor()

# 创建一个jsonb数组
data = [
    {"key1": "value1", "key2": "value2"},
    {"key3": "value3", "key4": "value4"}
]

# 将jsonb数组插入到数据库中
cur.execute("INSERT INTO your_table (jsonb_column) VALUES (%s)", (json.dumps(data),))

# 提交事务
conn.commit()

# 查询包含特定键值对的jsonb数组
cur.execute("SELECT * FROM your_table WHERE jsonb_column @> %s", (json.dumps({"key1": "value1"}),))
rows = cur.fetchall()
for row in rows:
    print(row)

# 关闭游标和连接
cur.close()
conn.close()
