//! Surface shared by the three cloud Postgres backends (Aurora, Cloud SQL, Flexible
//! Server).
//!
//! Everything here is cloud-only, so the module is gated once at its `mod` declaration
//! rather than attribute-by-attribute: a local-only build has no secret store to read
//! and no cloud handle to hand back.

/// would actually look for in `ALIEN_<NAME>_BINDING`.
