"I've been using PostgreSQL for years on small projects, and I have an
opportunity to migrate my company's websites from Oracle to an
open-source alternative. It would be good to be able to show the PHBs
that PostgreSQL is a viable candidate, but I'm unable to find a list
of high-traffic sites that use it. Does anyone know of any popular
sites that run PostgreSQL?"
