Peter is mixing issues here. How another application finds the right
libpq.so, libpqxx.so or whatever interface lib after someone moved the
PostgreSQL lib directory somewhere else has absolutely nothing to do
with how we make sure that our binary utilities like initdb, psql and so
forth are protected against using the wrong one in a multi-version
relocatable environment.

And that some platforms support relative rpath is nice handwaving, but
it doesn't get us anywhere.
