Surely this is not right. Neither collprovider nor the other fixed-length
fields following it in pg_collation are marked nullable, and most of them
are accessed as struct fields so that's not an easy thing to change.
The fact that the buildfarm didn't blow up is a bit odd. Maybe we're
missing some enforcement somewhere?
