PersistAnt’s relational driver over sqlx (PostgreSQL first).
PgBackend implements persistant_relational::RelationalBackend. The concrete
sqlx::PgPool is available through PgBackend::pool, so a program that wants
compile-time-checked sqlx::query! keeps it (D1, C+): this crate does not hide sqlx.
Failures are classified from the server’s SQLSTATE into persistant_relational::RelError.
