pub async fn init(url: &str, database: &str) -> Result<Pool, Error>Expand description
Open the admin pool against url (no database path — lands on the
connecting user’s default database, postgres), ensure database
exists, then open the application pool and apply the inline
schema. Idempotent across cold and warm starts — re-running
against an already-bootstrapped database is a no-op (every CREATE
uses IF NOT EXISTS).
