//! Integration tests for the `sqlx` tracing-layer front-end (PostgreSQL backend).
//!
//! Runs the `test-sqlx-08` `basic_postgres` example as a subprocess and asserts
//! on its report. Requires the PostgreSQL container from the repo-root
//! compose.yml (`docker compose up -d postgres`, host port 5439). Skips locally
//! when nothing listens there; on CI the postgres service is mandatory, so a
//! missing server fails instead.
//!
//! The example uses `$1` positional placeholders, so this also pins their
//! normalization to `?` - the asserted bucket texts are identical to the
//! sqlite ones in `sql_sqlite.rs`.
