Tom Lane 707263542e Fix parse location tracking for lists that can be empty. 
The previous coding of the YYLLOC_DEFAULT macro behaved strangely for empty
productions, assigning the previous nonterminal's location as the parse
location of the result.  The usefulness of that was (at best) debatable
already, but the real problem is that in list-generating nonterminals like
	OptFooList: /* EMPTY */ { ... } | OptFooList Foo { ... } ;
the initially-identified location would get copied up, so that even a
nonempty list would be given a bogus parse location.  Document how to work
around that, and do so for OptSchemaEltList, so that the error condition
just added for CREATE SCHEMA IF NOT EXISTS produces a sane error cursor.
So far as I can tell, there are currently no other cases where the
situation arises, so we don't need other instances of this coding yet.

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.  Changes between all PostgreSQL releases are recorded in the
file HISTORY.  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/.
