Planet PostgreSQL blog posted twice on postgresql.org

Hi,

I removed a post from planet postgres to get it updated with some
corrections that we made after publishing. That worked from fine on
planet postgres, but now postgresql.org has two copies of the blog, one
with a broken link. This broken link has also been posted to twitter
(somebody commented on it) along with the good link.

The blog is: pgBackRest File Bundling and Block Incremental Backup

Anything we can do about this?

Thanks!
