Description Tom Lane 2004-08-24 21:59:02 UTC

Description of problem: Transactions committed just before the last
checkpoint before a database crash may be lost, in whole or in part,
after recovery.

Version-Release number of selected component (if applicable): All PG
versions 7.1-7.4

How reproducible: Difficult to reproduce due to narrow window of
vulnerability, but a fairly reproducible test case is described at
http://archives.postgresql.org/pgsql-hackers/2004-08/msg00650.php

Steps to Reproduce:
1.  See link
  
Actual results: Lost data

Expected results: No lost data

Additional info: This is repaired in the most recent upstream
releases.  For AS2.1, we are using the 7.1 series of PG releases, for
which there is no upstream patch; we will need to backport a fix.

Comment 1 Tom Lane 2005-02-10 18:28:47 UTC

Fix made for postgresql-7.1.3-6.rhel2.1AS.  A side-effect of the fix
is that the commit_delay functionality is disabled ... but I doubt
anyone will miss it.
