在python中统一编码postgres中的文本列

import psycopg2

# 建立数据库连接
conn = psycopg2.connect(
    host="your_host",
    port="your_port",
    database="your_database",
    user="your_username",
    password="your_password"
)

# 创建游标对象
cur = conn.cursor()

# 执行SQL查询
cur.execute("SELECT * FROM your_table")

# 获取查询结果
rows = cur.fetchall()

# 关闭游标和连接
cur.close()
conn.close()

cur.execute("SET client_encoding TO 'UTF8'")

cur.execute("CREATE TABLE your_table (your_column TEXT ENCODING 'UTF8')")

your_value = "你好"
encoded_value = your_value.encode('utf-8')
cur.execute("INSERT INTO your_table (your_column) VALUES (%s)", (encoded_value,))
