According to the Pareto principle, also known as the 80/20 rule, roughly 20% of the efforts yield 80% of the results. In the context of becoming a PostgreSQL developer, here are 20% of the important topics that can help you get started and make significant progress:

  1. Relational Database Concepts: Understand the fundamentals of relational databases, including tables, relationships, normalization, and primary/foreign keys.
  2. SQL (Structured Query Language): Gain proficiency in SQL, the language used to interact with relational databases. Learn about querying, data manipulation, and data definition statements.
  3. Data Types and Operators: Familiarize yourself with the different data types available in PostgreSQL and the operators used to manipulate and compare data.
  4. Table Creation and Management: Learn how to create tables in PostgreSQL, define column constraints, and manage indexes and constraints for efficient data storage.
  5. Query Optimization: Explore techniques for optimizing SQL queries, including proper indexing, query planning, and analyzing query performance.
  6. Joins and Subqueries: Understand various types of joins (inner, outer, cross) and subqueries to retrieve data from multiple tables effectively.
  7. Functions and Stored Procedures: Learn how to create and use user-defined functions and stored procedures to encapsulate complex logic in the database.
  8. Triggers: Gain knowledge of triggers and how they can be used to enforce data integrity rules or automate actions based on certain database events.
  9. Views: Understand the concept of views and how they can provide a virtual representation of data from one or more tables.
  10. Transactions and Concurrency Control: Familiarize yourself with transactions and how to ensure data consistency and handle concurrent access to the database.
  11. Security and Authentication: Learn about user management, authentication methods, and implementing secure access control to protect sensitive data.
  12. Backup and Recovery: Understand the importance of regular backups and practice restoring databases to ensure data availability and disaster recovery.
  13. Indexing: Gain knowledge about different types of indexes and how to choose and create them to improve query performance.
  14. Advanced SQL Techniques: Explore advanced SQL concepts such as window functions, common table expressions (CTEs), and recursive queries.
  15. Performance Tuning: Learn techniques for monitoring and optimizing the performance of PostgreSQL databases, including query profiling and tuning.
  16. Replication and High Availability: Understand the concepts of replication and high availability to ensure data redundancy and minimize downtime.
  17. Full-Text Search: Explore PostgreSQL’s full-text search capabilities to implement powerful text search features in your applications.
  18. JSON and NoSQL Features: Familiarize yourself with PostgreSQL’s support for JSON data and its ability to handle NoSQL-like use cases.
  19. PostGIS (Geospatial Data): If you’re interested in working with geospatial data, learn about PostGIS, an extension that enables spatial database capabilities in PostgreSQL.
  20. Community Resources and Best Practices: Stay connected with the PostgreSQL community, participate in forums, read documentation, and follow best practices to enhance your skills and stay up to date.

Remember that this list provides a starting point, and there’s much more to learn and explore as you progress in your journey as a PostgreSQL developer.
