What this sounds like is you are using two different locale settings
in the 8.2 and 8.4 installations. Postgres' string comparisons follow
whatever the rules of the locale are. Try "show lc_collate" to see
what the setting is.
In 8.2 the locale is determined at initdb time, but in 8.4 you can
set it when creating a database.
