Tom Lane a6cc7db9a6 Repair "Halloween problem" in EvalPlanQual: a tuple that's been inserted by 
our own command (or more generally, xmin = our xact and cmin >= current
command ID) should not be seen as good.  Else we may try to update rows
we already updated.  This error was inserted last August while fixing the
even bigger problem that the old coding wouldn't see *any* tuples inserted
by our own transaction as good.  Per report from Euler Taveira de Oliveira.

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 several language
bindings, including C, Perl, Python, and Tcl, as well as a JDBC
driver.

The ODBC and C++ interfaces have been moved to the PostgreSQL Projects
Web Site at http://gborg.postgresql.org for separate maintenance.

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
ftp://ftp.postgresql.org/pub/.  For more information look at our web
site located at http://www.postgresql.org/.
