JD, Why would you do this? Why do we care? We are relational, they -- well I don't know what they are.
One of the goals of The PostgreSQL Conference Series is the expand the knowledge of the community and to extend a hand to secondary communities, inviting them learn, collaborate and drink with us. By inviting MongoDB, we are doing exactly that. It is my sincerest hope that we can get a lot of the MongoDB users to better understand our ways, as cranky and old-school as they may be and in return, we will learn some of their ways, perhaps making PostgreSQL even better.
Consider, what if our upcoming SQL/MED support in 9.1 had a foreign data wrapper that was optimized for MongoDB?
Remember folks, CFP is still open
And of course, many thanks to the PostgreSQL Conference Sponsors:
