  • Rich Indexing
  • Integration with Visual Studio Code
  • Integration with JSONB – Binary version of the JSON data format.
  • Use the programming language of your choice, like Ruby on Rails or Python.
• Horizontal scaling with Hyperscale. This allows very high-performant distributed data use across many PostgreSQL instances. You can scale easily to hundreds of nodes with no application rewrites.
• It gives Performance recommendations based on how you use the data and the database.
• There are features to monitor and detect disruptive events that can hamper performance, which you can then act.
• Managed cloud functionalities (at no extra cost) like automatic database patching, automatic backups, and built-in monitoring.
• This is ideal for online transactions processing, so can be used in the financial industry, can be integrated with mathematical applications like R and MATLAB.
• Governments use Postgres for geometric data, (also known as GIS, or G-I-S). There's a powerful GIS extension called PostGIS, which provides hundreds of functions to process geometric data in various formats
• PostgreSQL can be configured for automatic failover, zero downtime upgrades, and full redundancy.
