However, if your installation was upgraded from a previous major

action to prevent possible data loss due to a now-fixed bug in

Fix <application>pg_upgrade</>'s handling of TOAST tables
(Bruce Momjian)

<para>
The <structname>pg_class</>.<structfield>relfrozenxid</> value for
TOAST tables was not correctly copied into the new installation

<para>
This error poses a significant risk of data loss for installations
that have been upgraded with <application>pg_upgrade</>. This patch
corrects the problem for future uses of <application>pg_upgrade</>,

processed with a buggy version of <application>pg_upgrade</>.
