pub async fn apply_migrations(pool: &PgPool) -> Result<(), MigrationError>Expand description
Apply all pending migrations bundled in this crate’s
migrations/ directory.
Out-of-band only. Wave 0 ships a placeholder 0001_*.sql
(just SELECT 1;) so the machinery is exercised; wave 3
replaces it with the real schema. Callers: tests + a future
ff-migrate CLI. Must NOT be called from
PostgresBackend::connect.
