Michael Paquier 902276ff13 Fix handling of OpenSSL's SSL_clear_options This function is supported down to OpenSSL 0.9.8, which is the oldest version supported since `593d4e4` (from Postgres 10 onwards), and is used since `e3bdb2d` (from 11 onwards). It is defined as a macro from OpenSSL 0.9.8 to 1.0.2, and as a function in 1.1.0 and newer versions. However, the configure check present is only adapted for functions. So, even if the code would be able to compile, configure fails to detect the macro, causing it to be ignored when compiling the code with OpenSSL from 0.9.8 to 1.0.2. The code needs a configure check as per `a364dfa`, which has fixed a compilation issue with a past version of LibreSSL in NetBSD 5.1. On HEAD, just remove the configure check as the last release of NetBSD 5 is from 2014 (and we have no more buildfarm members for it). In 11 and 12, improve the configure logic so as both macros and functions are correctly detected. This makes NetBSD 5 still work on already-released branches, but not for 13 onwards. The patch for HEAD is from me, and Daniel has written the version to use for the back-branches.

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:

	https://www.postgresql.org/download

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
https://www.postgresql.org/download/.  For more information look at our
web site located at https://www.postgresql.org/.
