Numpy and database queries?

Question

Python

Getting familiar with the numpy library. I tried to make a simple script for collecting data from the database. For some reason it gives an error:

TypeError: 'numpy.int32' object does not support indexing

The script itself:

import psycopg2
import numpy as np

selectDealersSQL = "SELECT dealer_id, name FROM public.dealers"
selectCountPointsSQL = 'SELECT count(*) FROM dealer_points WHERE point_type IN (1,2) AND active = TRUE AND dealer_id = %s'

conn = psycopg2.connect("dbname='***' user='nmurad' host='***.***.***.***' password='***'")
cur = conn.cursor()
cur.execute(selectDealersSQL)
rows = cur.fetchall()

points = np.array([], dtype='int8')

for row in rows:
    points = np.append(points, row[0])

for point in points:
    cur.execute(selectCountPointsSQL, point)

It gives the following error:

TypeError Traceback (most recent call last)
in ()
16
17 for point in points:
---> 18 cur.execute(selectCountPointsSQL, point)
TypeError: 'numpy.int32' object does not support indexing

Please help.
