That's what it's supposed to do.

If you want noise, try VACUUM VERBOSE ANALYZE.
Anyway: don't the EXPLAIN numbers change once you've done VACUUM
ANALYZE? How many rows are there matching 'someuser', anyhow?
It might be useful to see the planner's statistics, too -- try
select attname,attdisbursion,s.*
from pg_statistic s, pg_attribute a, pg_class c
where starelid = c.oid and attrelid = c.oid and staattnum = attnum
and relname = 'FOO';
(substitute name of interesting table for FOO)
