Motion transitioned from CockroachDB to Postgres due to escalating costs and operational challenges, particularly with migrations and ETL processes. The migration revealed better performance with Postgres for many queries, despite some initial advantages of Cockroach’s query planner. The move ultimately streamlined operations and resolved numerous UI and support issues experienced with CockroachDB.

Recall.ai faced significant performance issues with their Postgres database due to the high concurrency of NOTIFY commands used during transactions, which caused global locks and serialized commits, leading to downtime. After investigating, they discovered that the LISTEN/NOTIFY feature did not scale well under their workload of tens of thousands of simultaneous writers. They advise against using LISTEN/NOTIFY in high-write scenarios to maintain database performance and scalability.

The article explores a mysterious issue related to PostgreSQL's handling of SIGTERM signals, which can lead to unexpected behavior during shutdown. It discusses the implications of this behavior on database performance and reliability, particularly in the context of modern cloud architectures. The author highlights the importance of understanding these nuances to avoid potential pitfalls in database management.
