I wonder why the pre-existing core PostgreSQL organization (not super-clear to me which this is) did already have these trademarks in the top handful of countries/jurisdictions. Rather than wait for someone else to try and then get in a potentially expensive fight. PostgreSQL has been around for 25 years, there has been ample time to figure that out, right?

Sounds like in the US at least they _do_ have trademarks, the other organisations filing was declined by the PTO because of the existing mark, see the documents linked in this comment: https://news.ycombinator.com/item?id=28513942

Likely because it is tedious (think watching paint dry) and expensive. And except if you take a shotgun approach to the service/goods classes you register in, you are still going to have exposure (in the US you need to provide proof of use down the road so its a non.starter there).
