Lc_collate and lc_ctype have been per-database settings since server version 8.4, but pg_upgrade was still treating them as cluster-wide options. It fetched the values for the template0 databases in old and new cluster, and compared them. That's backwards; the encoding and locale of the template0 database doesn't matter, as template0 is guaranteed to contain only ASCII characters. But if there are any other databases that exist on both clusters (in particular template1 and postgres databases), their encodings and locales must be compatible. Also, make the locale comparison more lenient. If the locale names are not equal, try to canonicalize both of them by passing them to setlocale(). We used to do that only when upgrading from 9.1 or below, but it seems like a good idea even with newer versions. If we change the canonical form of a locale, this allows pg_upgrade to still work. I'm about to do just that to fix bug #11431, by mapping a locale name that contains non-ASCII characters to a pure-ASCII alias of the same locale. No backpatching, because earlier versions of pg_upgrade still support upgrading from 8.3 servers. That would be more complicated, so it doesn't seem worth it, given that we haven't received any complaints about this from users.
