postgrel执行VACUUM报VACUUM cannot run inside a transaction block

 

在python脚本里执行：

    

1 　　 sql_gp1 = "VACUUM dwd_access_record_inout_temp"
2     sql_gp2 = "delete from dwd_access_record_inout_temp t where t.indate > (select now()::timestamp-interval '36 hour')"
3     conn = gputil.connect(logger,target_host,target_user,target_password,target_db)
4     #gputil是自己导入pgdb写的模块
