CreateQueueTicket passed 9 arguments to QueueTicketInsertSQL, which
only has 8 placeholders (state is a hardcoded 'QUEUED' literal in the
SQL, not $4) -- every real queue-ticket creation against PostgreSQL
failed with 'mismatched param and argument count'. Found by actually
running the opt-in Postgres integration suite (previously never
exercised locally, per its own gating) rather than trusting the unit
tests, which mock the driver and can't catch a placeholder-count
mismatch. Verified fixed against a real postgres:17-alpine container.
