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.
