I have been using PostgreSQL for my project repository, because it is free and easy to use. My manager is trying to decide if he should use a commercial database such as Oracle or PostgreSQL for a giant information repository for the corporate. He asked me what is the scaleability on PostgreSQL. I don't have the answer. So far, I have been very pleased with PostgreSQL, but I'm only using it for my project.
Does anyone have any information on this? Has anyone done any comparisons?
