Database Performance Issue on PostgreSQL 7

There is an issue in versions of PostgreSQL prior to 8.0 that causes the database to do a full table scan rather than an index lookup for many of the database queries performed by Confluence. This will cause Confluence to slow significantly the more data it has stored.

While we fully support Confluence on PostgreSQL 7, we highly recommend upgrading to version 8.0 or higher for this reason.
