Given the principle that WP schema only contains tables that are actually
used by Core, it's pretty clear that this is plugin territory.

There aren't enough different columns between post, page & attachment to
warrant this approach.

Plus, the meta tables offer a lot more flexibility.

Also, there's nothing preventing you from building a custom table with
certain columns that you need to do complex queries with.
