I think last_vacuum tracks regular vacuums, not vacuum full.
This maintenance procedure seems like something that would have been
appropriate back with postgres 7.something, anyway. Do you have any
evidence that you need it at all? autovacuum works reasonably well
for most people, and in any case it seems unlikely that you need a
daily vacuum full or reindex.
