Can Postgres handle 1 billion rows?
As commercial database vendors are bragging about their capabilities we decided to push PostgreSQL to the next level and exceed 1 billion rows per second to show what we can do with Open Source. To those who need even more: 1 billion rows is by far not the limit – a lot more is possible. Watch and see how we did it.
Is PostgreSQL NoSQL?
At the end of the day, PostgreSQL is still a relational data model and does not have all the features of a NoSQL database such as an aggregation pipeline. When you try to model data in PostgreSQL, the best practice is to still default to a relational model and only use JSON when it makes sense.
How popular is PostgreSQL?

What is difference between MySQL and PostgreSQL?
PostgreSQL is an object-relational database, while MySQL is purely relational. This means PostgreSQL offers more complex data types and allows objects to inherit properties, but it also makes working with PostgreSQL more complex. PostgreSQL has a single, ACID-compliant storage engine.
MySQL is free and open-source software under the terms of the GNU General Public License, and is also available under a variety of proprietary licenses. MySQL was owned and sponsored by the Swedish company MySQL AB, which was bought by Sun Microsystems (now Oracle Corporation).
Why choose SQL Server over Postgres?
PostgreSQL doesn’t support in-memory database creation. SQL Server uses an optimistic strategy to handle memory-optimized tables, which means they can participate in transactions along with ordinary tables. Memory-based transactions are faster than regular ones, and this allows a drastic increase in application speed.
