RE : BUG #3519: Postgres takes the wrong query plan resulting in performance issues

I'm sending in attachment the output of the explain analyze command and the create table statements of tables involved in the query.
Yes, I have vacuumed and analyzed my database this morning before running the query.

I'm sorry; I thought it was a bug with the optimizer, that's why I used the reporting bug

Thanks for your help

To help you with that, we'd need to see the EXPLAIN ANALYZE output of
the query, and the CREATE TABLE statements of the tables involved in the
query and their indexes.

Have you vacuumed and ANALYZEd your database recently?

PS. This is not a bug. Please don't use the bug reporting form for
classic performance issues.
