What is the db table "sent_notifcations" needed for?

Hi there,

I have an gitlab installation running on a selfhosted sever.
unfortunately I had a system crash and since then the table “sent_notifcations” is no longer accessable.
I suspect a log commit corruption on postgresql. Fortunately gitlab kept running without any complains.

My question would be, if someone could tell me if a restore of just the named table itselfe would harm the gitlab system integrety. unfortunately I discovered this to late so the latest working backups I have are about one month old.

Thank you in advance for any help regarding this topic.
