I don't think so.

I'm not sure I buy that. All -rpath does is add a directory to the search
path that the program consults at runtime for its shared libraries. So
it's just an alternative in place of
hard-coded into dynamic linker
/etc/ld.so.conf
LD_LIBRARY_PATH
but it's the terminally accurate alternative.
What does happen if the referenced library gets updated? Nothing. -rpath
doesn't reference any libraries, it just suggests to the runtime linker
where it might look for one. I don't want to use it to find system
libraries, I just want psql to find libpq, and the right libpq, and I want
to relieve installers from having to fiddle around with these settings.

I don't think so.
