The query planner in PostgreSQL before 8.0.11 8.1 before 8.1.7 and 8.2 before 8.2.2 does not verify that a table is compatible with a "previously made query plan" which allows remote authenticated users to cause a denial of service (server crash) and possibly access database content via an "ALTER COLUMN TYPE" SQL statement which can be leveraged to read arbitrary memory from the server.
