I assume he is saying that you would have problems having that set all
the time. You would need to set it only before running pg binaries,
which is a pain.

The point is that we want someone to be able to do an install, and then
be able to move the pgsql directory. When we use rpath, the installed
binary has a hardcoded path for the libraries.

We don't. By default it is /usr/local/pgsql/lib, which isn't standard.
I see static linking as perhaps the only clean solution for relocatable
installs that require no user manipulation.
