Обсуждение: ERROR: _mdfd_getrelnfd: cannot open relation pg_class: No such file or directory

I don't understand the error message in detail but my opinion is that
there is something really broken - so I would backup your databases,
initialize the pgdata with initdb again and then restore it.

Maybe somebody else understands/knows what the error means.

Hi,
Thanks for your reply,

I have noticed that the file that contains pg_class table has been
disappeared. I don't know how.

Anyway, I have restored from my backup.

Thanks again.
