Hi, Running 9.1 on Windows 10, upgrading to 10 with pg_upgrade.
"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.-

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. 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.
