Heikki Linnakangas df27d76d32 Disconnect if socket cannot be put into non-blocking mode 
Commit 387da18874 moved the code to put socket into non-blocking mode
from socket_set_nonblocking() into the one-time initialization
function, pq_init(). In socket_set_nonblocking(), there indeed was a
risk of recursion on failure like the comment said, but in pq_init(),
ERROR or FATAL is fine. There's even another elog(FATAL) just after
this, if setting FD_CLOEXEC fails.

Note that COMMERROR merely logged the error, it did not close the
connection, so if putting the socket to non-blocking mode failed we
would use the connection anyway. You might not immediately notice,
because most socket operations in a regular backend wait for the
socket to become readable/writable anyway. But e.g. replication will
be quite broken.

Backpatch to all supported versions.

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/.
