These Postgres-specific operations should optimize into nothing, if they
create and remove the same collation.
I believe we need to implement `CreateCollation.reduce()` that returns an
empty list when the other operation is a `RemoveCollation` for the same
`(locale, provider, deterministic)` tuple. This can take inspiration from
`CreateModel.reduce()` which does similar when reducing to a
`DeleteModel`.
