Error "could not open relation with OID XXXXXXX"

[sykerzner]

I have not seen anyone talk about this issue, so I wanted to start a thread. I already started a ticket with Veeam #07524680

Looks like something is wrong with the database on one of our of our client's VBR servers (v12.2 Postgresql). The backup jobs are failing with an error "could not open relation with OID XXXXXXX".

We get the same error when browsing the console and clicking on the Backups or Backup Copy section.
We can check the History section - which is how i know the backups are failing with the same error.

It seems like the Backup Copy jobs are working, although the last one was from yesterday, so I don't know what will happen tonight.

Looking at the logs, you can see where the query to the database failed. Support is leaning towards a performance. timeout issue, which don't really match. There is no timeout (the error happens right away), the error is too consistent, and the performance is perfect.

Has anyone seen anything similar?
