Well, it's just like anything else in an open-source database: you can change the code however you want, but the fallout from that is on you. In the case at hand, you might be able to do what you want by adding something along the line of GRANT USAGE ON FOREIGN DATA WRAPPER postgres_fdw TO @extowner@ WITH GRANT OPTION; to the extension install script. But nobody's researched whether that's reasonable from a security standpoint, or whether it will play nicely with dump/reload, etc etc. regards, tom lane
