Tom Lane d7cff12c4c Add macro PGWARNING, and make PGERROR available on all platforms.
We'd previously noted the need for coping with Windows headers
that provide some other definition of macro "ERROR" than elog.h
does.  It turns out that R also wants to define ERROR, and
WARNING too.  PL/R has been working around this in a hacky way
that broke when we recently changed the numeric value of ERROR.
To let them have a more future-proof solution, provide an
alternate macro PGWARNING for WARNING, and make PGERROR visible
always, not only when #ifdef WIN32.

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/.
