Tom Lane 3d3218aa3d Back-patch fix and test case for bug #7516.
Back-patch commits 9afc648111 and
b8fbbcf37f.  The first of these is really
a minor code cleanup to save a few cycles, but it turns out to provide
a workaround for the misoptimization problem described in bug #7516.
The second commit adds a regression test case.

Back-patch the fix to all active branches.  The test case only works
as far back as 9.0, because it relies on plpgsql which isn't installed
by default before that.  (I didn't have success modifying it into an
all-plperl form that still provoked a crash, though this may just reflect
my lack of Perl-fu.)

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/.
