Hello!
A week ago I reported this, but haven't got any good help. I am trying
to repeat.
Postgres 6.4.2 on Solaris. Query:
SELECT p.subsec_id FROM positions p, central cn, shops sh, districts d WHERE cn.pos_id = p.pos_id AND d.city_id =
2 AND cn.shop_id = sh.shop_id AND sh.distr_id = d.distr_id AND cn.date_i >= current_date - '7
days'::timespan
I am not publishing here my tables, but the structure is obvious. There
is central database, which only knows shop_id, and shop only knows its
district, and district knows city. I want to count distinct p.subsec_id for
one city. With the query, postgres eats all memory and dies.
I played with the query, and found I can remove (AND d.city_id = 2). The
query executes pretty fast (my database is small). I tried to get
d.city_id:
SELECT p.subsec_id, d.city_id FROM positions p, central cn, shops sh, districts d WHERE cn.pos_id = p.pos_id
AND cn.shop_id = sh.shop_id AND sh.distr_id = d.distr_id AND cn.date_i >= current_date - '7 days'::timespan
but postgres eats all memory and dies :(((
Memory leak? Other bugs?
Oleg.
