Revision 0176f8bea436e166654fb3e5d2d8a1ff42552f7a authored by Alvaro Herrera on 02 December 2013, 16:28:18 UTC, committed by Alvaro Herrera on 02 December 2013, 16:28:18 UTC
The backpatch of a95335b544d9c8377e9dc7a399d8e9a155895f82 to 9.2, 9.1 and 9.0 was incomplete, missing changes to xlog.c, primarily the call to TrimMultiXact(). Testing presumably didn't show a problem without these changes because TrimMultiXact() performs defense-in-depth work, which is not strictly necessary. It also missed moving StartupMultiXact() which would have been problematic if a restartpoing happened in exactly the wrong moment, causing a transient error. Andres Freund

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
