Pilot for real-container testing of db_engine_specs against actual databases (CockroachDB, CrateDB, Trino), via testcontainers-python. Existing unit tests mock the driver/dialect layer entirely, which cannot catch real SQL-compilation or type-mapping bugs -- e.g. #42899, where Trino emitted OFFSET before LIMIT for paginated queries. Runs nightly (.github/workflows/nightly-testcontainers.yml), not on every merge: container pulls and startup are slower and more flake-prone than the existing mocked unit tests, and this measures that cost/signal tradeoff before considering wider adoption. Building this surfaced two real bugs, fixed/documented separately: - The cockroachdb dialect was completely broken under SQLAlchemy 2.0 due to a dead upstream package -- fixed in #43501. - testcontainers-python's TrinoContainer.get_connection_url() returns the container-internal port instead of the Docker-mapped host port; worked around locally, filed upstream.
