Apparently this copy of libpq was built against a newer version of
OpenSSL than what you have installed locally.  The man page for
X509_get_signature_nid says it was added in OpenSSL 1.0.2, in case that
helps.  You need to find or build a version of Postgres that's intended
for your specific platform version.  Alternatively, maybe you would be
better off moving to a newer platform version, or at least installing
a newer OpenSSL version.  Anything older than 1.0.1 is considered
outright insecure these days.
