If you can't upgrade to 8.0 or 8.1 then at least consider using the latest version in the 7.4 branch (7.4.11). You're missing almost two years of bug fixes. http://www.postgresql.org/docs/7.4/static/release.html > I am running an application server over a database in which tables > contains at most a few thousands of records.

If not then it's accumulating a lot of dead tuples, which would cause performance to degrade. Are you vacuuming at all? See "Routine Database Maintenance Tasks" in the documentation for an explanation of what it is and why it's necessary. http://www.postgresql.org/docs/7.4/static/maintenance.html -- Michael Fuhr
