Tom Lane 60f1e6bc13 Fix poor errno handling in libpq's version of our custom OpenSSL BIO. 
Thom Brown reported that SSL connections didn't seem to work on Windows in
9.5.  Asif Naeem figured out that the cause was my_sock_read() looking at
"errno" when it needs to look at "SOCK_ERRNO".  This mistake was introduced
in commit 680513ab79, which cloned the
backend's custom SSL BIO code into libpq, and didn't translate the errno
handling properly.  Moreover, it introduced unnecessary errno save/restore
logic, which was particularly confusing because it was incomplete; and it
failed to check for all three of EINTR, EAGAIN, and EWOULDBLOCK in
my_sock_write.  (That might not be necessary; but since we're copying
well-tested backend code that does do that, it seems prudent to copy it
faithfully.)

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:

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