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.
