Tom Lane 1986ca5ce5 Fix race condition in multixact code: it's possible to try to read a 
multixact's starting offset before the offset has been stored into the
SLRU file.  A simple fix would be to hold the MultiXactGenLock until the
offset has been stored, but that looks like a big concurrency hit.  Instead
rely on knowledge that unset offsets will be zero, and loop when we see
a zero.  This requires a little extra hacking to ensure that zero is never
a valid value for the offset.  Problem reported by Matteo Beccati, fix
ideas from Martijn van Oosterhout, Alvaro Herrera, and Tom Lane.

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.

The JDBC, ODBC, C++, Python, and Tcl interfaces have been moved to the
PostgreSQL Projects Web Site at http://gborg.postgresql.org for separate
maintenance.  A Perl DBI/DBD driver is available from CPAN.

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/.
