Unfortunately, we don't have any way of dealing with different character
sets or locales in different tables. (AFAICT this is not practical
without implementing our own locale library, which would be an enormous
task; someday we will solve this problem, but don't hold your breath.)
So pg_shadow, pg_group, and pg_database are all risk spots.
I think the best advice is to limit your user/group/database names to
7-bit-ASCII if you are going to use different encodings in different
databases. That way, they'll look valid in all databases.
