Looks like from the test cases you posted, you're not actually benchmarking any *queries*, you're comparing the speeds of the procedural languages. And yes, PL/pgSQL is known to be a farily slow language. If you want fair benchmark results, you should instead concentrate on what databases are supposed to do: store and retrieve data; finding the most optimal way to execute complicated SQL queries. In most setups, that's where the majority of database processor time is spent, not procedure code. Regards, Marti
