This is why you should never ever trust an AI coding agent to produce good code.

PostgreSQL is quite terrible at OLAP, though. We got a few orders of magnitude performance improvement in some aggregation queries by rewriting them with ClickHouse. It's incredible at it.

My rule of thumb is: PG for transactional data consistency, Clickhouse for OLAP. Maybe Elasticsearch if a full-text search is really needed.
