DB schema clean-ups
|Reported by:||Denis-de-Bernardy||Owned by:||anonymous|
While looking into #9422, it occurred to me that some DB fields weren't necessarily used today. Namely:
links.link_category int(20) seems to be overridden by the terms schema.
The same goes for posts.post_category int(4).
It might be that they've been left around for obsolete plugins, though. In case this isn't the case, the attached patch, for 2.8 trunk, will remove them.
