Tom Lane c42e5fdcfa Cope with a deficiency in OpenSSL 3.x's error reporting. 
In OpenSSL 3.0.0 and later, ERR_reason_error_string randomly refuses
to provide a string for error codes representing system errno values
(e.g., "No such file or directory").  There is a poorly-documented way
to extract the errno from the SSL error code in this case, so do that
and apply strerror, rather than falling back to reporting the error
code's numeric value as we were previously doing.

Problem reported by David Zhang, although this is not his proposed
patch; it's instead based on a suggestion from Heikki Linnakangas.
Back-patch to all supported branches, since any of them are likely
to be used with recent OpenSSL.

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/.
