Note that this is done by Linux distributions, vanilla PostgreSQL doesn't use version-specific paths. The reason is that the PostgreSQL on-disk format is not forward-compatible. In order to upgrade from one Postgres version to the next, you need to have *both* versions installed at once. As annoying as it is, version-specific paths is a pretty foolproof way to enable that.
