Of course. I didn't say otherwise. I only say that it's useful in
that case. E.g. if you're using a dedicated partition for PG,
then a good solution is what I describe, rather than horrifyingly
trying to remove some random PG files, or when you cannot
temporarily move some of them and symlink from the PG partition.
I don't praise that kind of case, it should of course be avoided
by sane management. A bad management is not a reason for hiding
solutions to the problems that can happen!
