Subject: [pgadmin-support] Foreign Servers
Where should Foreign Servers appear in the Object Browser? I have two foreign servers defined, confirmed by querying information_schema.foreign_servers, but the Object Browser doesn’t show them in the schema they are defined, or any other place that I can see. I have Foreign Servers checked in Options->Browser->Display. I do see the foreign tables and foreign data wrappers.
