Hi thanks for all your answers.
Concerning the problem of the same "running time" I'm really surprised but I can confirm that the EXPLAIN ANALIZE time is different from the query execution time. probably it happen something like this: http://bytes.com/topic/postgresql/answers/422841-explain-analyze-total-runtime-walltime But we have tried to remove the fk constraints without any improvement Concerning the client problem, e have tried to execute the query directly on the server using psql. The difference is still in the order of seconds: around 10 ms VS 5000 ms many thanks... other suggestions? ivan and mauro -- Ti prego di cercare di non inviarmi files .dwg, .doc, .xls, .ppt.
