Needs Suggestion

Hi,<br />I am currently a student of IIT Bombay. I am doing a project on "Benchmark design". For that I need to measure
theperformance of various queries in databases. <br />I want to know how can we measure the execution time of a query
inPostgres (Explain analyze will not do). Also is there any tools available in Linux for measuring the performance of
queriesof databases such as Oracle 11g, Postgres, etc.<br /> Any suggestions will be very helpful.<br clear="all" /><br
