在Postgres中批量插入的最快方法是什么？

import psycopg2

# 连接到Postgres数据库
conn = psycopg2.connect(database="your_database", user="your_username", password="your_password", host="your_host", port="your_port")
cur = conn.cursor()

# 创建一个批量插入语句
insert_sql = "INSERT INTO your_table (column1, column2, column3) VALUES (%s, %s, %s)"

# 准备要插入的数据（以元组形式传递）
data = [(1, "value1", 3), (2, "value2", 4), (3, "value3", 5)]

# 执行批量插入
cur.executemany(insert_sql, data)

# 提交事务并关闭连接
conn.commit()
conn.close()
