Really. | http://smurf.noris.de/ > -- Although I am a PostgreSQL zealot, I have to admit that many PostgreSQL users have hidden behind the use of transactions in justifying the sometimes 2 - 3 times slower execution speeds in DML statements vs. MySQL. As Vadim points out in his comparison of COPY vs. INSERT, something is *wrong* with the time it takes for PostgreSQL to parse, plan, rewrite, and optimize. Now that MySQL has transactions through Berkley DB, I think its going to be harder to justify the pre-executor execution times. Just my two cents, Mike Mascari
