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.
