I see no reason to symlink to libpq_r if it is identical to libpq.
Operating systems are moving away from _r libraries, and I see no reason
to create one just for consistency with platforms that still use _r.
Basically, I don't like the confusion.
I agree with the goal of having a libpq_r if it is different from libpq.
This is going to require us to compile libpq twice and install libpq and
libpq_r. Can that be done cleanly? I don't see how we can get this
done before beta. Will we fiddle with this during beta?
