Does anyone use PostgreSQL in Production?

The number of Oracle users is huge and Oracle has the numbers available. The number of EnterpriseDB users is smaller but EnterpriseDB tracks those also. I would like to know how many people are using PostgreSQL in production and what kind of systems they are running.

If you monitor the some of the Postgres email lists, such as General, Jobs, and, maybe the Docs group, you can get a basic feel of some usage but only from the more verbal and connected in the community.

Does Forrester Research or Gartner track open source database usage? I haven't seen anything.

I know the community tracks things like downloads but that is incredibly misleading for production usage. Do you know anyone that is surveying or tracking these kinds of stats?
