Hello, Has this problem been fixed? I was under the impression that it had been, but I spent some 20 minutes now looking for code, commits, or patches in the archives, and I can't find anything relevant. Maybe it was fixed in some different way that's not so obviously connected? Thanks, -- Álvaro Herrera 48°01'N 7°57'E — https://www.EnterpriseDB.com/
