Tom Lane 8d8ff5f7db Improve error message for rejecting RETURNING clauses with dropped columns. 
This error message was written with only ON SELECT rules in mind, but since
then we also made RETURNING-clause targetlists go through the same logic.
This means that you got a rather off-topic error message if you tried to
add a rule with RETURNING to a table having dropped columns.  Ideally we'd
just support that, but some preliminary investigation says that it might be
a significant amount of work.  Seeing that Nicklas Avén's complaint is the
first one we've gotten about this in the ten years or so that the code's
been like that, I'm unwilling to put much time into it.  Instead, improve
the error report by issuing a different message for RETURNING cases, and
revise the associated comment based on this investigation.

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.  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/.
