如何通过 AWS Jupyter Notebook 查询（Postgres）RDS 数据库？

Question

I'm trying to query an RDS (Postgres) database through Python, more specifically a Jupyter Notebook. Overall, what I've been trying for now is:

import boto3

client = boto3.client('rds-data')

response = client.execute_sql(
    awsSecretStoreArn='string',
    database='string',
    dbClusterOrInstanceArn='string',
    schema='string',
    sqlStatements='string'
)

The error I've been receiving is:

BadRequestException: An error occurred (BadRequestException) when calling the ExecuteSql operation: ERROR: invalid cluster id: arn:aws:rds:us-east-1:839600708595:db:zprime

In the end, it was much simpler than I thought, nothing fancy or specific. It was basically a solution I had used before when accessing one of my local DBs. Simply import a specific library for your database type (Postgres, MySQL, etc) and then connect to it in order to execute queries through python.

I don't know if it will be the best solution since making queries through python will probably be much slower than doing them directly, but it's what works for now.

import psycopg2

conn = psycopg2.connect(database = 'database_name',
                        user =     'user',
                        password = 'password',
                        host =     'host',
                        port =     'port')

cur = conn.cursor()

cur.execute('''
            SELECT *
            FROM table;
            ''')

cur.fetchall()
