kumiko clean-test-dbs

kumiko clean-test-dbs [--dry-run]

Integration tests spin up a throw-away kumiko_test_<uuid> database per test worker. Clean shutdown drops them — but SIGKILLed runs (Ctrl-C, OOM, container crash) leak them.

This command lists every kumiko_test_* database on the connected Postgres and drops them (or, with --dry-run, just lists what it would drop).

Example

kumiko clean-test-dbs --dry-run
# would drop:
#   kumiko_test_abc123
#   kumiko_test_def456

kumiko clean-test-dbs
# ✓ dropped 2 stale test DBs

When to use

• Disk fills up (each test DB is ~10-50MB; they add up over a long iteration session)
• Periodically as a hygiene step

It’s safe to run while tests are active — the cleanup skips DBs that have an open connection.
