Tom Lane abe45a9b31 Fix EXPLAIN output for cases where parent table is excluded by constraints. 
The previous coding in EXPLAIN always labeled a ModifyTable node with the
name of the target table affected by its first child plan.  When originally
written, this was necessarily the parent table of the inheritance tree,
so everything was unconfusing.  But when we added NO INHERIT constraints,
it became possible for the parent table to be deleted from the plan by
constraint exclusion while still leaving child tables present.  This led to
the ModifyTable plan node being labeled with the first surviving child,
which was deemed confusing.  Fix it by retaining the parent table's RT
index in a new field in ModifyTable.

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/.
