Last pacman package had the force flag set, and it was highly annoying to try keeping a local version installed. It always wanted to upgrade it. I tried adding it to IgnorePkg, but it wasn't much better, it still asked me if I wanted to upgrade pacman at each pacman -Syu. So, I'm not sure if it's correct, but I made IgnorePkg really ignore the package. And for me at least, it's much better that way :)
