It's perfectly normal for a query to run faster after a VACUUM ANALYZE than 
after an ANALYZE ... after all, you just vacuumed it, didn't you?

If you're demonstrating some other kind of behavioural difference, then please 
post the results of EXPLAIN ANALYZE for the two examples.

Oh, and we should probably shift this discussion to the PGSQL-PERFORMANCE 
list.
