为什么我在 pgAdmin 中看不到我在 python 中创建的表

Question

我在 jupyter 笔记本中使用 psycopg2 创建了一个表。这已成功完成，我没有收到任何错误。现在我想在 pgAdmin 界面中查看该表，但它没有出现在那里。为什么？

这是我写的代码：

import psycopg2
from psycopg2 import Error
try:
    connection = psycopg2.connect(user = "postgres",
                                  password = "nadav256",
                                  port = "5432",
                                  database = "postgres")
    cursor = connection.cursor()

    create_table_query = '''CREATE TABLE demo2
          (ID INT PRIMARY KEY,
          TIME           VARCHAR(50),
          ACCABS         REAL,
          BARO           REAL); '''

    cursor.execute(create_table_query)
    connection.commit()
    print("Table created successfully in PostgreSQL ")
except (Exception, psycopg2.DatabaseError) as error :
    print ("Error while creating PostgreSQL table", error)
finally:
    #closing database connection.
        if(connection):
            cursor.close()
            connection.close()
            print("PostgreSQL connection is closed")

这是我得到的输出：

Table created successfully in PostgreSQL 
PostgreSQL connection is closed
