我有一个大脚本，结果是数据存储在一个dataframe，然后在csv。然后csv被打开并写入PostgreSQL。但有一个问题，一列的数据类型是int4，打开csv后列格式是“文本”。我不能改变数据库中的数据类型，他们必须有完全一样的int。告诉我请如何做到这一点。

total.to_csv("C:/Users/.../total_type19.csv", index = False, sep =';')

conn5 = psycopg2.connect(dbname='', user='',
                       password='', host='', port = '')
cursor5 = conn5.cursor()

with open("C:/Users/.../total_type19.csv", "r",encoding = 'utf-8') as file:
    reader = csv.reader(file, delimiter = ";")
    for row in reader:
        # print(row)
        cursor5.execute(
            'INSERT INTO interaction_fillword (test_id,data_size,data_matrix, data_words_selection, data_colors, data_answers) VALUES(%s,%s, %s, %s, %s, %s)',
            (row[0], row[1], row[2], row[3], row[4], row[5]))

conn5.commit()

test_id列必须为int4格式

['312229', "['[{from:[3,4],to:[7,4],color:2},{from:[3,6],to:[10,6],color:3},{from:[5,8],to:[9,8],color:5},{from:[5,11],to:[10,11],color:6},{from:[1,0],to:[1,11],color:0},{from:[10,1],to:[10,6],color:4},{from:[3,0],to:[8,0],color:1}],']", '[\'["v","b","c","c","a","h","i","e","r","s","f","j"],["d","i","w","s","s","r","i","f","y","y","f","c"],["j","b","m","w","d","q","s","q","t","w","e","m"],["x","l","m","m","l","s","o","x","d","q","u","t"],["l","i","f","p","l","a","c","e","t","u","t","o"],["m","o","s","b","r","t","c","y","z","v","r","r"],["j","t","x","c","a","r","t","a","b","l","e","o"],["b","h","k","m","d","b","r","y","q","u","i","y"],["y","è","s","r","h","g","o","m","m","e","w","h"],["u","q","p","c","s","c","x","b","k","e","d","o"],["u","u","o","l","q","v","y","y","b","y","e","h"],["r","e","o","u","j","b","u","r","e","a","u","k"]],\']', '[\'"#ff0000","#00fe00","#0000ff","#d2ea9a","#407f76","#211f95","#e1f233"\']', '[\'"place","cartable","gomme","bureau","bibliothèque","feutre","cahier"\']']

这是csv中的一行代码的例子。看起来很糟糕，但它应该是这样的
