If you use an older slot of the kernel or postgres, you need to put them in world to stop them from being depcleaned. I don't know how postgres upgrades work in gentoo, but deleting the kernel sources are usually no big deal unless you plan to re-compile that particular version. Just make sure you have your config in /boot or something. I would assume that after adding any other programs you use to world, any libraries it wants to remove are actually not in use.
