postgres optimization

hi, for php-db list users, i'm not sure if this is off-topic. please inform me if it is. i'd like to ask anyone who have worked with PostgreSQL for any advise on how to optimize its performance. i have a database that has a few tables. one of which may contain more than 50,000 records in the future. thanks! ric -- ================================================================== Note: The information contained in this message may be privileged and confidential and protected from disclosure.
