Or if the user later uninstalls those libraries -- which can happen
automatically when nothing in the packaging system depends on them any
longer.
But i don't see what the conflict is if they're installed in
PGHOME/lib as long as the installer doesn't fiddle with
/etc/ld.so.conf or set any environment variables. The binaries should
just be built with an rpath pointing to that directory or ship with a
startup script which puts that directory in LD_LIBRARY_PATH. Whether
you want to append, leaving the system directories ahead of the
one-click installed libraries, or prepend so the linker always uses
your libraries would depend on how you want it to behave. Setting
rpath is equivalent to prepending I believe.
