No, not really. But you can (and should) run EXPLAIN <your query> to
obtain the execution plan for that query, und you can show us this plan
(and the table-definition for all included tables). Maybe someone is able
to tell you what you can do to speed up your query.
And yes, have you tuned your postgresql.conf?
