Sure it does. That's two whole generations of client tools. For
example, at that point, pgAdmin3 won't reliably run on any supported
platform, so it won't be a problem if we break it.
If we clearly mark the old function names as deprecated aliases, client
tools will gradually move to the new names.
Counter-argument: moving the directory is going to break many tools
anyway, so why bother with function aliases?
