The case with CONCURRENTLY is different though: the option will never work on system catalogs so we have to skip them. Echoing with others on this thread, I don't think that we should introduce a different behavior on what's basically the same grammar. That's just going to lead to more confusion. So REINDEX DATABASE with or without a database name appended to it should always mean to reindex the catalogs on top of the existing relations. -- Michael
