lost statistics; analyze needs to execute twice

Hi,

pgsql 8.3.7 and 8.4.0

when i issue an "immediate shutdown" the statistics on all tables disappear=
...
and when i try to recover them via an analyze; (on all tables on the
database) the result is nothing...
i have to exexute the analyze commands twice to compute the statistics


jd=3D# select relname, n_live_tup, n_dead_tup from pg_stat_user_tables
where relname =3D 'bpprovee';
 relname  | n_live_tup | n_dead_tup
----------+------------+------------
 bpprovee |        111 |          0
(1 row)

jd=3D# select version();
                                              version
