Tom Lane 59a4a571d3 Make plpgsql complain about conflicting IN and OUT parameter names. 
The core CREATE FUNCTION code only enforces that IN parameter names are
non-duplicate, and that OUT parameter names are separately non-duplicate.
This is because some function languages might not have any confusion
between the two.  But in plpgsql, such names are all in the same namespace,
so we'd better disallow it.

Per a recent complaint from Dan S.  Not back-patching since this is a small
issue and the change could cause unexpected failures if we started to
enforce it in a minor release.

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/.
