The db PR only unit-tested arg parsing; this adds executable proof that
dump/restore actually works end to end.
- test/db-integration.sh: stands up two throwaway Postgres containers whose
superusers DIFFER by construction (src_super vs dst_super), seeds a known
checksummable fixture, runs the real `rig db dump`/`rig db restore`, and
reads the rows back out — proving both invariants db.sh cares about: the
code reads the container's OWN $POSTGRES_USER/$POSTGRES_DB (a hardcoded
`postgres` would break on the non-default source superuser), and
--no-owner --no-acl makes the dump portable across differing superusers (a
plain dump would abort under ON_ERROR_STOP=1 on the missing role). Also
asserts default-outfile naming, restore idempotency (--clean --if-exists),
and the named-[db] scratch-database path. Skips cleanly (exit 0) when Docker
is absent/unreachable or root is unobtainable; always cleans up via trap.
- ci.yml: separate `db-integration` job on ubuntu-latest (Docker preinstalled),
kept apart from the fast shellcheck+cli.sh `check` job so an image pull can't
slow lint feedback.
- README: "Verifying a dump/restore actually works" — the safe manual
round-trip against a real Coolify container via a fresh scratch db, echoing
"a backup you have never read back is not yet a backup."
