〇動作検証用コード

import psycopg2

con = psycopg2.connect("dbname=test host=localhost user=test password=test")

try:
  cur= con.cursor()
  sql = "select message_id, message from messages"
  cur.execute(sql)

  for row in cur.fetchall():
    print(row)

except psycopg2.Error as er:
    print('psycopg2.Error:', er)
cur.close
con.close
