For those who don’t know what PostgreSQL is and why you should learn it, let me give you some basic introductions. PostgreSQL is an open-source object-relational database management system (ORDBMS), which was developed at the University of California, Berkeley, in 1996. It is now managed by the PostgreSQL Global Development Group. PostgreSQL was implemented in C Programming language, and unlike MySQL, which has multiple storage engines, it just has a single storage engine.
The best thing about PostgreSQL is that it confirms ANSI SQL standard but also adds some more power, which will help you to write better queries.
PostgreSQL is the world’s most advanced open-source relational database. It has a strong reputation for its reliability, data integrity, and robustness. Because of this, PostgreSQL is one of the most popular and widely used database systems in the world. Companies that use PostgreSQL include Apple, Cisco, Spotify, Fujitsu, Skype, Netflix, and IMDb. PostgreSQL also comes with many features aimed to help developers build applications, administrators to protect data integrity and build fault-tolerant environments and help you manage your data no matter how big or small the dataset.
In addition to being free and open-source, PostgreSQL is highly extensible, which makes it the darling database of modern new developers. It’s also used as a cost effective option to store historical data on many companies. For example, they can use Oracle for storing real-time data and move historical data to postgres for cost saving.

What’s the difference between SQL and PostgreSQL?
This is one of the common doubts among all IT professionals. Some misunderstood that SQL and PostgreSQL are the same which is not correct.
SQL is a language. Specifically, the “Structured Query Language”
PostgreSQL is one of several database systems, or RDMS (Relational Database Management System). PostgresSQL is one of several RDBMSs, others of which are Oracle, Informix, MySQL, and MSQL.
All of these RDBMSs use SQL as their language. Each of them has minor variations in the “dialect” of SQL that they use, but it’s all still SQL. For example, SQL Server has the TOP keyword which is not available in Oracle.
Similarly, PostgreSQL has many functions that are not available in other databases. Earlier, I have shared about T-SQL vs Pl/SQL vs SQL and this is the same, instead of T-SQL you have PostgreSQL.
And, if are preparing for coding interviews and you need more questions not just queries but also database and SQL related questions from other topics like indexes, joins, group by, aggregation, and window functions then you can also checkout Grokking the SQL Interview book to prepare better.
This book is one of the specially designed book to prepare you for SQL interviews by answering popular questions. You an also use discount code friends20 to get 20% discount now.
That’s all about some of the best online courses to learn the PostgreSQL database in 2023. As I said, PostgreSQL is very popular and used everywhere. If you are exploring RDBS for your new project, PostgreSQL can be a good option.
