Is there any way to repair this database without losing data? I have the last backup 2 months ago and I don’t want to lose the created topics.

[תמונה] RikoDEV: public.scheduler_stats You got lucky that this table contains just sidekiq stats and nothing really important. You can try to remove this table rows and then try to trigger another backup. Hope only this table was affected :crossed_fingers:

The problem is that postgresql crashes when I try to clean this table. discourse=# DELETE FROM scheduler_stats; PANIC: corrupted item pointer: 10992 server closed the connection unexpectedly This probably means the server terminated abnormally before or while processing the request. The connection to the server was lost. Attempting reset: Succeeded.

Oh noes. Does a TRUNCATE on this table also fails?

Looks like a corrupt database to me based on the error message?
