Tom Lane 7bf40ea0d0 Avoid using SplitIdentifierString to parse ListenAddresses, too. 
This gets rid of our former behavior of forcibly downcasing
the postmaster's hostname list and truncating the elements to
NAMEDATALEN.  In principle, DNS hostnames are case-insensitive
so the first behavior should be harmless, and server hostnames
are seldom long enough for the second behavior to be an issue.
But it's still dubious, and an easy fix is available: just use
SplitGUCList instead.

AFAICT, all other SplitIdentifierString calls in the backend are
OK: either the items actually are SQL identifiers, or they are
keywords that are short and case-insensitive.

Per thinking about bug #16106.  While this has been wrong for
a very long time, the lack of field complaints means there's
little reason to back-patch.

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/.
