** Comment includes the following statement: "And Core is not even a non-profit, it's nothing (there's no legal entity behind). Or the PostgreSQL Association of Canada, which is an association which could definitely grant exclusive trademark use to a given entity, as it is not scrutinized by a country's Ministry, as a Fundación in Spain is." 
** Comment includes the following statement: "We believed this form of a non-profit is much stronger and better to protect a Community like Postgres from potential rogue actors. As an aside, we contemplate honorary (non-voting) members. We believe is a good thing. I'd also propose the same for Core --I believe at least Bruce Momjian should be named as such." 
** Comment includes the following statement: "I agree that we need to enhance the [Fundación PostgreSQL] website and give more visibility to the people behind the foundation. We will do so shortly." 
** Comment includes the following statement: "I have personally voiced many concerns about different aspects of the governance and workings of the Community. And in 2019 a very clear and significant case was raised when some dispute over IP (a domain name) surfaced. In this case, we declined used of the domain name following Core's request, but raised --again-- concerns over the governance of Postgres."
