I would identify the process retaining WAL, validate the risk of removing or advancing any replication dependency, then recommend a safe mitigation and document the root cause. Describe your approach to diagnosing a slow query reported by a customer. I would gather the query, parameters, schema details, row counts, execution plan, PostgreSQL version, and workload context. I would use EXPLAIN ANALYZE to identify expensive operations, assess indexes and statistics, test a safe optimization, and explain both the immediate workaround and durable fix. How do you turn an incomplete customer report into an actionable engineering escalation? I ask targeted questions about expected versus actual behavior, timestamps, project configuration, logs, reproducible steps, and recent changes. I then create a minimal reproduction, capture evidence, state the impact and scope, and provide engineering with a concise hypothesis and any known workaround. What steps would you take after a failed database migration with possible schema drift? I would pause further writes or deployments where appropriate, compare the intended migration history with the live schema, and determine whether the failure was transactional. After taking or validating backups, I would prepare an idempotent recovery plan, test it in a safe environment, and clearly communicate risks before applying changes. How would you support a high-impact incident for a Japanese-speaking customer while collaborating with a global engineering team? I would acknowledge the issue promptly in Japanese, establish impact and urgency, and provide clear status updates with confirmed facts and next steps. In parallel, I would maintain an English incident summary for engineering with timestamps, logs, reproduction details, and customer impact, ensuring both audiences receive accurate and empathetic communication.
