That's also what I think is the most likely explanation. Maybe the
lesson here is that we ought to be adding all locales at initdb time,
not all distinct collations. That would also get us a dozen or so
identical English variants, and so on, just like with glibc. I don't
especially want that, but it seems like it might be better from a
stability point of view. After all, CLDR gives guarantees about the
stability of locales, not collations.
