This seems like a linking issue with the packaging or the
distribution.  X509_get_signature_nid is new as of OpenSSL 1.0.2, so
visibly your version of libpq.so has been compiled with OpenSSL 1.0.2,
but only an older version of OpenSSL is present, causing the
dependency failure.

Right. OP wrote this:

Operating system:   CentOS Linux release 7.1.1503 (Core)

which is something that we don't support. Users must update the OS along with
PostgreSQL. I always build the packages by using the very latest update set of
the OS pacakges.

Alternatively, users can rebuild the packages using the SRPMs provided.

There was a discussion of maintaining each RHEL minor release separately, but
that would be *a lot of* work, which is I want to avoid, so I rejected it.
