Troubleshooting PostgreSQL

In Chapter 11, Deciding on Useful Extensions, we learned about some useful extensions that are widely adopted and that can give your deployment a real boost. Following this up, you will now be introduced to PostgreSQL troubleshooting. The idea is to give you a systematic approach to inspecting and fixing your system.

In this chapter, the following topics will be covered:

  • Approaching an unknown database
  • Gaining a brief overview
  • Identifying the key bottlenecks
  • Handling storage corruption
  • Inspecting broken replicas

Keep in mind that many things can go wrong, so it is important to professionally monitor the database.
