While this doesn't exactly answer your question, I use this little tidbit of information when "selling" people on PostgreSQL. PostgreSQL was chosen over Oracle as the database to handle all of the .org TLDs information. While I don't believe the company that won was chosen solely because they used PostgreSQL vs Oracle ( vs anything else ), it does go to show that PostgreSQL can be used in a large scale environment. Another tidbit you can use in this particular case: I was involved in moving www.ljworld.com, www.lawrence.com, and www.kusports.com from a Sybase backend to a PostgreSQL backend back in 2000-2001. We got roughly a 200% speed improvement at that time and PostgreSQL has only improved since then. I would be more than happy to elaborate on this migration off list if you would like. kusports.com gets a TON of hits especially during "March Madness" and PostgreSQL has never been an issue in the performance of the site. --------------------------------- Frank Wiles <[EMAIL PROTECTED]> http://www.wiles.org --------------------------------- ---------------------------(end of broadcast)--------------------------- TIP 8: explain analyze is your friend
