Yes, the cost is cool, if I turn off enable_hashjoin, I get
a very hight cost. But the runtime is smaller (in a bigger
query, which have around 20 row on output, and 2-3 subselect
and 3-4 join).

So, upgrade is strongly recommended? :) Debian package is
not so good, the backup script doesn't work (in an earlier
debian package). I tried to backup the database (I have
daily backup) before upgrading, but restoring from this was
too hard for me, because the postgres server didn't started
(he/she thinks I haven't got backup :).
