描述
v0.8.3 通过gh-ost执行包含``的语句，提示语法错误，去除`后正常
旧版本执行是正常的，不确定是哪个版本，docker镜像id：04ec51bc001f，构建于4 weeks ago

重现
配置开启ghost

osc_min_table_size = 0
ghost_on = true

执行语句

ALTER TABLE `archer_test`.`osc_test` DROP COLUMN `xx`;

结果

Execute: Error 1064: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '\`xx\`' at line 1.
