pg_class.reltuples not reset by VACUUM?

I thought that VACUUM ANALYZE would always restore some sense of reality
to the internal statistics for a table. However ...

# select count(*) from job_queue;

count
-------
834
(1 row)

# select reltuples from pg_class where relname = 'job_queue';

reltuples
-----------
206277
(1 row)

# vacuum analyze job_queue;

# select reltuples from pg_class where relname = 'job_queue';

reltuples
-----------
2062xx (slightly larger number)
(1 row)

This is of concern to me mostly because:

# explain select * from job_queue;

NOTICE: QUERY PLAN:

Seq Scan on job_queue (cost=0.00..5989.77 rows=206277 width=95)

Obviously, the optimizer thinks that the table has 200k rows in it!
