This seems like some sort of data corruption, because 827 is an index on
a system catalog, namely pg_default_acl_role_nsp_obj_index.
I don't have an Ubuntu system around, but I've tried on debian 9.6 and
it works just fine. I very much doubt Ubuntu is broken.
My guess the system lost the file for whatever reason (admin error,
filesystem bug, power-loss/crash, ...).
