In PostgreSQL, the slow query log is a feature that allows you to log queries that take longer than a specified threshold to execute. This log helps you identify and optimize queries that may be causing performance issues in your database. Let’s see how we can use it.

Database observability is crucial for maintaining optimal performance and reliability in modern software systems. It enables organizations to monitor key metrics such as query execution time, resource utilization, and transaction throughput, facilitating the early detection and resolution of issues like slow queries or resource contention. Let's see how to build it.

Choosing a database is hard, however, maintaining it afterward is even harder. In this post, we talk about elements to focus on, tooling, monitoring, and other aspects of keeping the database up and running.
