Michael Paquier a12c75a104 Fix SSL test for libpq connection parameter channel_binding
When compiling Postgres with OpenSSL 1.0.1 or older versions, SCRAM's
channel binding cannot be supported as X509_get_signature_nid() is
needed, which causes a regression test with channel_binding='require' to
fail as the server cannot publish SCRAM-SHA-256-PLUS as SASL mechanism
over an SSL connection.

Fix the issue by using a method similar to c3d41cc, making the test
result conditional.  The test passes if X509_get_signature_nid() is
present, and when missing we test for a connection failure.  Testing a
connection failure is more useful than skipping the test as we should
fail the connection if channel binding is required by the client but the
server does not support it.

PostgreSQL Database Management System
=====================================

This directory contains the source code distribution of the PostgreSQL
database management system.

PostgreSQL is an advanced object-relational database management system
that supports an extended subset of the SQL standard, including
transactions, foreign keys, subqueries, triggers, user-defined types
and functions.  This distribution also contains C language bindings.

PostgreSQL has many language interfaces, many of which are listed here:

See the file INSTALL for instructions on how to build and install
PostgreSQL.  That file also lists supported operating systems and
hardware platforms and contains information regarding any other
software packages that are required to build or run the PostgreSQL
system.  Copyright and license information can be found in the
file COPYRIGHT.  A comprehensive documentation set is included in this
distribution; it can be read as described in the installation
instructions.

The latest version of this software may be obtained at
