ouch. I didn't realize that. -1 to RH for that policy. -rpath is
*EXACTLY* the right solution for this sort of problem, I've always
*HATED* stuff that relies on ld.so or equivalent, or even worse,
LD_LIBRARY_PATH .... sigh.

maybe the postgresql91-libs should supercede the ld.so.conf.d file from
previous versions so there would be only one such .conf file, pointing
everyone at the latest installed version. otoh, if you removed 9.1, I
don't know how that would be able to put a previous version back, ugh.
