Michael Paquier 102689827f Trim regression test expected output for xml 
This commit reduces the number of expected output files for the "xml"
test from three to two (well, mostly one, see below for details).

xml_2.out existed to handle some differences in output due to libxml2
2.9.3, due to some error context missing (085423e3e3).  This file is
removed, by tweaking the XML inputs to trigger the same error patterns
for the problematic 2.9.3 and other libxml2 versions.  This part is
authored by Tom Lane.

xml_1.out (no libxml2 support) is reduced in size by adding an \if query
that exits the test early.  This still checks NO_XML_SUPPORT() through
xmlin().  The rest of the test is skipped if XML input cannot be
handled by the backend.  This part has been written by me.

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/.
