Integration tests and developer machines can exercise the postgres backend by
installing the helper from crates.io and running it before make test:
cargo install --locked pg-embed-setup-unpriv
pg_embedded_setup_unpriv
The helper stages a PostgreSQL distribution with unprivileged ownership, so the
postgresql_embedded crate can start temporary clusters without root access.
After invoking the helper, run make test to execute sqlite, postgres, and
wireframe-only suites; the postgres jobs automatically reuse the staged
binaries. Both server binaries honour the same MXD_DATABASE and --database
values, allowing the helper to be re-run once and then switching between
cargo run --bin mxd and cargo run --bin mxd-wireframe-server without
additional setup. Refer to docs/pg-embed-setup-unpriv-users-guide.md for
cluster path customization and privilege troubleshooting details.
