Hello (again),

I read some documentation about tuning postgresql.conf but i didn't
find information clearly about how to use GeQo. It seems to help planner
but using a lot of CPU, and is usefull only for big join.
Per default, geqo = true, but in which case, geqo is usefull and in

If someone have some documentation or help about that.

Have you read the GEQO section in the docs?
