之前使用中断电过，执行备份有如下提示，
** Invoke gitlab:backup:create (first_time)
** Invoke gitlab_environment (first_time)
** Execute gitlab_environment
** Invoke environment (first_time)
** Execute environment
** Execute gitlab:backup:create
** Invoke gitlab:backup:db:create (first_time)
** Invoke gitlab_environment
** Execute gitlab:backup:db:create

Tasks: TOP => gitlab:backup:db:create
怀疑postgresql数据库损坏，但是尝试修复也没有有效解决问题。
没有备份过，现在计划无备份恢复，网上没找到很有用的资料，有哪位大神可以指导一下
