To be completely precise, it's not enough to have lc_collate=C, you also
need to not have indexed columns with individually specified non-default
collations. i.e. what matters is not so much the database setting, but
the actual collation being used for indexed columns (because it's the
collation that determines the order in which values appear in the
index).
