我们无法连接到 PostgreSQL 实例,我们必须重新启动 PostgreSQL 服务才能连接到实例,但几天后我们开始收到同样的错误。
日志显示以下错误

当我检查服务状态时,它显示以下详细信息
postgres: postgres utilitydb [local] startup waiting
postgres: postgres utilitydb [local] startup waiting
postgres: postgres utilitydb [local] startup waiting
postgres: postgres utilitydb [local] startup waiting
postgres: postgres utilitydb [local] startup waiting
postgres: postgres utilitydb [local] startup waiting
postgres: postgres utilitydb [local] startup waiting

我知道我需要检查数据库中的锁,但日志中提供的信息并不那么详细。PostgreSQL 系统表中没有 oid = 0 的数据库。
我该如何调试这个问题?
任何帮助,将不胜感激。
