Well, that's quite interesting, because pg_dump ought to read all the same catalogs that pg_upgrade is failing to read. So I'm not quite sure what's going on there. Nonetheless, your path forward is clear: use pg_dump (or better pg_dumpall) and then load the output into a freshly initdb'd v12 installation. It'll be a bit slower than the pg_upgrade way, but it'll work. regards, tom lane
