Best Resources to Learn PostgreSQL

PostgreSQL also known as Postgres, is a powerful, open source object-relational database system with over 30 years of active development that has earned it a strong reputation for reliability, feature robustness, and performance. It is a free and is the most advanced open source database system emphasizing extensibility and SQL compliance.

What is PostgreSQL?

PostgreSQL is the most advanced open-source database in use today, delivering more features and better performance than all competitors. The software is under constant development to work towards improving this fantastic functionality even further.

With an ever-expanding API set and a huge community of users, developers, and contributors alike, it’s hard not to find your dream app with PostgreSQL!

The major benefit of using Postgres rather than a generic RDBMS (e.g., MySQL/MariaDB) goes beyond just its flexibility or long history. Scaling Postgres on Linux allows you to leverage the power of B-tree indexes for added speed without compromising on data integrity. GPII (Granular Page Isolation) feature allows you to use huge pages for I/O-intensive workloads.

It’s also worth mentioning that PostgreSQL is horizontally scalable and can handle a large number of reads and writes. This makes the database particularly beneficial for online applications, which are constantly being updated with new data from users.

Postgres has over several thousand community contributors working to add more modern language support such as Python as well as integrations with many other platforms like R, Ruby, PHP, Django, Rails (Ruby on Rails), NodeJS etc., resulting in faster development times than ever before!

Nearly all open-source databases suffer from some kind of performance issue or bug at some point in time and by using PostgreSQL you should be safe in the knowledge that any issues will be solved rapidly.

PostgreSQL doesn’t require the developer to use any proprietary APIs and is completely open-source and freely available on most platforms (even without requiring a download for Linux). So if you are used to MySQL or even SQLite, you should find that PostgreSQL has a much friendlier interface.

The PostgreSQL community not only fixes bugs but also frequently offers new features for its users. Many of the bug-fixes have already been incorporated into OpenStack Essex/Folsom releases with some coming in later releases as well!

Why You Should Use PostgreSQL?

Here’s why the Postgres developers themselves recommend using it:

It has an advanced level data types, powerful data integrity with checksums for each data block, extremely scalable on multicore and parallel systems. It is fully ACID compliant and supports a full range of powerful query operators with boolean support, joins, aggregates etc.
