In this chapter, we learned about PostgreSQL development. We discovered how PostgreSQL is a popular DBaaS among the clouds and explored the good features of PostgreSQL through various application environments such as NodeJS, Django, PostGIS, and PostgREST. Next, we explored the administration of PostgreSQL by understanding the PostgreSQL architecture, PostgreSQL HA clusters, and PostgreSQL performance. Later, we learned the definition and/or principles of PostgreSQL database monitoring and introduced various DevOps tools for PostgreSQL. Finally, we developed an understanding of popular PostgreSQL database testing frameworks.
In the next chapter, we will learn how to set up a PostgreSQL RDS on a famous cloud – AWS – for ATM machines. This RDS will then be used in the remaining chapters of this book.
