"Once upon a time" there was a bug in our automatic role creation procedure that did not mask vowels with accent (used in Italian language), like "ò, è" and the result was a role with an empty name. We are now upgrading to 10, and pg_dumpall exits complaining with this role, showing its name (with mis-encoded UTF-8 accented vowel) as an invalid utf-8 character. Trying to get rid of the role, that can't be deleted with a drop role because of the empty name, I did delete from pg_authid where oid = nnnn Role disappeared from role list. At the next execution of the pg_upgrade it complains that role "nnnn" does not exist while dumping a trigger function. I tried remove the privilege from function ACL, but "role nnnnn does not exists". Is there a way to recreate the deleted role, either as a dummy, so I can finish upgrade? Is there another way to bypass the problem? Any help would be appreciated. Cheers, Moreno.- >Is there a way to recreate the deleted role, either as a dummy, so I can finish upgrade? I can't really suggest how to recreate the dummy role, but I do have an alternate solution. Most probably pg_dump is complaining that role 'xxx' owns some tables. IIRC the complain was about "role <oid> does not exist" In the meantime I was able to pg_dump single databases (5 in total, one of them complaining about the role not existing but dumped with all data in its place) and, with my surprise (since I was convinced that pg_dump was working inside a single transaction) I found all roles (all but the "failing" one) at their place in the new server. So, lesson learned: don't mess with system catalogs before RTFM :-)))))) So you can use the attached script and add 'AND a.rolname = 'xxx' to the WHERE clause. Then as a superuser you can use ALTER TABLE xyz OWNER TO new_owner for each table found. I'll keep it, so if something similar happens maybe it can come in hand..... Thanks for your time Moreno.-
