I am looking for any information regarding the approval of PostgreSQL by any United States government entities. I am specifically looking for approval on a DOD (Department of Defense) or DADMS (Defense Automated Document Management System) list. However any information that is provided, even if it is unrelated to those two, would be appreciated.
FYI - We are looking to use Postgres for a military contract project and we were curious as to how the approval might go. If there is evidence of Postgres being used previously, we would feel better about our chances.
