I'd bet a nickel this is caused by El Capitan's "System Integrity
Protection" deciding that your psql does not need the libpq version
it asked for and should get linked to /usr/lib/libpq.dylib instead
(which of course is several PG versions behind ...)

SIP is potentially a good idea, but until they get the policies it
enforces worked out, it's about where SELinux was ten years ago: the
first thing you do is turn it off, if you want to get any work done.
Right now it's an absolute disaster for anyone doing software
development work.

Here's what I have bookmarked about turning it off:

If turning off SIP doesn't fix things, we'll need to look closer.
