PostgreSQL version: 8.4
Operating system: ubuntu linux
Description: pg_upgrade fails when it should not.
Details:
pg_upgrade from 8.4 to 9.0 fails with the following error message.
old and new cluster lc_collate values do not match
on 8.4 show lc_collate outputs
------------
en_NZ.utf8
(1 row)
on 9.0 it outputs
------------
en_NZ.UTF8
(1 row)
So the difference seems to be in capitalization. Presumably they are the
same collation with "different" names so it strikes me as odd that
pg_upgrade would balk and refuse to upgrade the database.
pg_upgrade should be able to tell that these are the same collations and go
ahead with the upgrade.
It also should give some indication of how to overcome the problem.
