### Event ID

_No response_

The failure is reported from sentry/db/postgres/base.py while processing monitors.monitor_consumer. Compare the sentry_monitor schema and migration state for is_upserting, then reproduce the 25.7.0 check-in path; done means the consumer processes check-ins without the UndefinedColumn error.
