At least for the libraries, the point of the 'postgresql' subdir IMO
is to keep backend-loadable extensions separate from random libraries.
It's not great that we may fail to do that depending on what the
initial part of the library path is.

I could get behind allowing the user to specify that path explicitly
and then not modifying it; but when we're left to our own devices
I think we should preserve that separation.
