postgresql 使用 plpythonu 发送邮件及短信

闲来无事,自己写了个 postgresql 小监控程序,使用 plpythonu 实现了发送邮件和短信.现把发送邮件和短信的函数记录一下,以防忘记.

邮件服务的配置参考<>

CREATE EXTENSION IF NOT EXISTS plpythonu ;
CREATE EXTENSION IF NOT EXISTS plpython2u ;

    cmds = 'echo "' + pi_text + '" | /bin/mailx  -s "' + pi_subject + '" '+ pi_receiver  
  else:

  (status, output) = commands.getstatusoutput(cmds)
	
  return status
