Enum StorageBackend 

pub enum StorageBackend {
    Sqlite,
    Postgres {
        url: String,
        pool: StoragePoolSection,
    },
}

Type-state projection of StorageSection with cross-field invariants enforced.

StorageSection is deserialized from config.toml with relaxed shape so existing user configs continue to load — backend: String, url: Option<String>. That means a misconfigured backend = "postgres" with no url only fails at daemon startup with a string-mismatch error, and callers downstream of the parse have to keep re-checking the invariant.

StorageBackend is the parsed form: variants carry exactly the fields they require, so it is impossible to construct a Postgres variant without a URL or to ask for a pool configuration in a Sqlite variant. Use StorageSection::parsed at the boundary; downstream code matches on the enum.
