We are now working on database check mechanism in our application. The situation is when server shutdown abnormally, the postmaster.pid file still exists when reboot, But the PostgreSQL database itself may not be damaged. We just do not want to restore from backups when the database is still good even if server shutdown abnormally. If the PostgreSQL database records are damaged for sure when server reboots, then the restoration should be executed automatically.
So, is there any way or tool to automatically check the consistency status of PostgreSQL database when server starts up(like the DBCC in SQL server)?
