Since many of us use postgresql as our database manager of choice, this
posting in http://postgresql.org/news.html contains interesting news,
so, quoting from their site:
2002-10-06 - PostgreSQL 7.2.3 Released In order to address a potentially
critical bug in the VACUUM code, the PostgreSQL Global Development Group
is releasing v7.2.3 of PostgreSQL.
This release includes a fix for a serious problem that has affected all
7.2.* releases: if a VACUUM command is run by a non-superuser, it is
sometimes possible for the system to prematurely remove old transaction
log data (pg_clog files). This can result in data becoming
unrecoverable. All 7.2.* installations are urged to update to 7.2.3 as
soon as possible.
Other changes include;
* Prevent non-superuser from increasing most recent vacuum info
(Tom)
* Handle pre-1970 date values in newer versions of glibc (Tom)
* Fix possible hang during server shutdown
* Prevent spinlock hangs on SMP PPC machines (Tomoyuki Niijima)
* Fix pg_dump to properly dump FULL JOIN USING (Tom)
Good luck,
