Обсуждение: Exhausted memory

I have a big trouble! :-((

I make some big sql request on lot of table (about 12, but I tried with
less). Postgres take a lot of time (more than 10 minutes) to compute my
request. I trie the same request with the same table on MSAccess and it
take 2 seconds ?!?

I tried to create some index, but it wasn't better.

If you have some idea, send my it.

    What does the 'explain' command show you?  Do you have appropriate
INDICES in place...?
