But I feel like I'm REALLY close with pg_repack and I just don't understand enough about the system internals to nudge it to correctness and need some expert assistance to tap it in the hole. The only "system metadata" that would need changing is pg_class.relhasoids. However, it's certainly necessary to rewrite all the physical table rows (and hence all the table's indexes). I don't know a lot about pg_repack, but I'm a bit skeptical that it can really make that transparent. I'm even more skeptical that it could almost support it except this obvious use-case never occurred to the developers. I suspect that either the support already exists but you missed it, or else there's some fundamental stumbling block. Maybe go discuss this with the pg_repack developers? (Maybe they read pgsql-general, but I wouldn't count on it.) regards, tom lane
