This article describes How To Install PostgreSql 12.2 1 on Microsoft Windows Server 2019

PostgreSQL is a powerful, open source object-relational database system that uses and extends the SQL language combined with many features that safely store and scale the most complicated data workloads. The origins of PostgreSQL date back to 1986 as part of the POSTGRES project at the University of California at Berkeley and has more than 30 years of active development on the core platform.

PostgreSQL has earned a strong reputation for its proven architecture, reliability, data integrity, robust feature set, extensibility, and the dedication of the open source community behind the software to consistently deliver performant and innovative solutions. PostgreSQL runs on all major operating systems, has been ACID-compliant since 2001, and has powerful add-ons such as the popular PostGIS geospatial database extender. It is no surprise that PostgreSQL has become the open source relational database of choice for many people and organisations.

PostgreSQL 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. For example, you can define your own data types, build out custom functions, even write code from different programming languages without recompiling your database!

PostgreSQL tries to conform with the SQL standard where such conformance does not contradict traditional features or could lead to poor architectural decisions. Many of the features required by the SQL standard are supported, though sometimes with slightly differing syntax or function. Further moves towards conformance can be expected over time. As of the version 12 release in October 2019, PostgreSQL conforms to at least 160 of the 179 mandatory features for SQL:2016 Core conformance. As of this writing, no relational database meets full conformance with this standard.

PostgreSQL is the first database management system that implements multi-version concurrency control (MVCC) feature, even before Oracle. The MVCC feature is known as snapshot isolation in Oracle.

PostgreSQL is a general-purpose object-relational database management system. It allows you to add custom functions developed using different programming languages such as C/C++, Java, etc.

PostgreSQL is designed to be extensible. In PostgreSQL, you can define your own data types, index types, functional languages, etc. If you don’t like any part of the system, you can always develop a custom plugin to enhance it to meet your requirements e.g., adding a new optimizer.

If you need any support, an active community is available to help. You can always find the answers from the PostgreSQL’s community for the issues that you may have when working with PostgreSQL. Many companies offer commercial support services in case you need one.

Many companies have built products and solutions using PostgreSQL. Some featured companies are Apple, Fujitsu, Red Hat, Cisco, Juniper Network, etc.
