Hmm, this got me to wondering.

If I recall OS X ships with its own version of Postgres.

Can you search for what libpq versions you might have installed on your
machine?

Also from your first post you have:

PostgreSQL 9.5.4_1

This is not Postgres community version number(the _1 part), so where did
you get it and/or install it?
