Hi, I would like to know if Postgres has shared memory like Library Cache (avoid to do parse the same sql), Dictionary Cache (metadata information), Sort Area and so on? Oracle has this structures. And Postgres? I couldn't find anything about memory on Postgres. Thanks. _______________________________________________________ Yahoo! Mail - Sempre a melhor opção para você!
