Add a test case for ticket #464 but leave it commented out for now. We will fix this problem when VACUUM is rewritten. (CVS 1105) (check-in: 7ba8dc9b1e user: drh tags: trunk)

Do all WHERE clauses tests, even if an index is used for lookup so that we know the test cannot be FALSE. The test might end up being NULL in which case it would need to be treated as false. Ticket #461. (CVS 1103) (check-in: 5aea81488b user: drh tags: trunk)
