Advantages & Disadvantages of PostgreSQL

  • by

PostgreSQL is an enterprise-grade open-source software for managing databases. It can be used with SQL as well as JSON for non-relational and relational queries that allow for extensibility and SQL compliance. PostgreSQL provides the most advanced types of data and optimization of performance features that are available only in high-end commercial databases such as Oracle or SQL Server. It is also referred to as Postgres.

It is supported by a seasoned group composed of programmers who’ve made significant contributions to making it an extremely solid DBMS system.

The history of PostgreSQL

PostgreSQL (initially named Postgres) was developed by a professor of computer science Michael Stonebraker and his team. It is now one of the most popular open-source databases.

Here is a brief overview of PostgreSQL:

The INGRES concept was first developed in 1977.
Michael Stonebraker and his colleagues created Postgres-86.
Real-time support for ACID and PL/pgSQL since 1990.
In -1995, Postgres95 was released as a Postgres95.
The Postgres95 Re-released Postgres95 with the name PostgreSQL 6.0 – – 1996
MVCC, GUC, Join syntax Controls and Procedural Language Loader added- 1998-2001
Version 7.2 to 8.2: Included features such as Schema support, nonblocking VACUUM, Roles and dblink 2002-2006
PostgreSQL 8.4 made public in 2009
PostgreSQL 9.0 launched in 2010
NYCPUG (New York City PostgreSQL User Group) joins PgUS (United States PostgreSQL association)from 2013
PGconf organized-2014

Specifications of PostgreSQL

Here are the main characteristics of PostgreSQL:

Aids developers in creating applications.
Administrators can create an environment that is fault-tolerant by securing integrity of data.
Compatible with a variety of platforms and the most popular Middleware and languages.
It has the most advanced locking mechanism.
Multi-version support for concurrency controls.
Advanced Server-Side Functionality for Programming.
Conforms to that of the ANSI SQL standard.
Complete support for the client-server networking architecture.
Replication SSL based on triggers and logs.
Server standby and high availability.
Object-oriented and compatible with ANSI-SQL2008.
Support for JSON allows linking to other data stores such as NoSQL that act as a federated hub to polyglot databases.

Benefits of PostgreSQL

Here are the major benefits and advantages of PostgreSQL:

PostgreSQL is able to run dynamic websites and web applications as an LAMP stack option.
The write-ahead feature of PostgreSQL is a reliable database.
PostgreSQL sources are made accessible with an open-source license. This permits you to have the freedom to modify, utilize and apply it according to the requirements of your business.
PostgreSQL can support geographic objects, which means it can be used for geographical information and services that are based on location. systems.
PostgreSQL can support geographic objects, so it could be utilized as a geospatial information storage system for services that are based on location and geoinformation systems.
For those who want to learn about Postgres, they don’t require much instruction as it’s easy to make use of.
Administration and maintenance are low-maintenance for embedded and enterprise usage of PostgreSQL.

The disadvantages of PostgreSQL

Below are the disadvantages/limitations of PostgreSQL:

Postgres isn’t owned by any one company. Therefore, it has struggled to get its name noticed despite having all the features and comparable with other DBMS systems.
Speed improvements made to the database will require more effort than MySQL because PostgreSQL is focused on compatibility
Many open-source apps have support for MySQL however they might not be able to support PostgreSQL
In terms of performance indicators, MySQL is less efficient than MySQL.

Applications of PostgreSQL

The following are the most popular applications made by PostgreSQL:

Financial Industry

PostgreSQL is a perfect DBMS system to use in the financial industry. Additionally, it is ACID certified, making it a perfect option to use for OLTP (Online Transaction Processing). It can also be used for conducting analytics on databases. It is able to be coupled with mathematical software such as Matlab as well as R.

GIS data from the Government

PostgreSQL is a an extremely powerful GIS which is known as “PostGIS”. The extension offers hundreds of functions that process geometric data in a variety of formats. PostGIS is extremely standard-compliant. Additionally, by using QGIS as well as GeoServer and GeoServer, the Open Source community provides the most effective method of handling Geodata.


Today, industrial companies are using the PostgreSQL client to improve their business processes overall. They can also enhance the performance of supply chains through the use of the open source DBMS as a backend for storage. It helps companies reduce the operational cost of their businesses.

Internet technology as well as NoSQL

If your site has to manage hundreds or even thousands of requests per second Scalability is surely a major problem. In this case, Postgre is the most effective solution.

PostgreSQL is compatible with modern web frameworks, including Django, Node.js,

Hibernate, PHP, etc. It also has replication capabilities that allow you to expand as many databases as you like.
Data from science

There are Terabytes of data when you’re involved in research or scientific projects. This is why it is essential to manage the data as efficiently as efficiently as is possible. To do this, PostgreSQL offers wonderful analytical capabilities as well as a powerful SQL engine. This allows you to manage a huge amount of data easily.


A brief introduction of PostgreSQL: PostgreSQL is an enterprise-class open-source database management system.
PostgreSQL (initially known as Postgres) was invented by computer science professor Michael Stonebraker and his team
One of the advantages of PostgreSQL is its compatibility with various platforms and all major languages as well as middleware.
POSTGRES Server is free and open-source software. This means that you won’t have to pay to use this service.
The most notable PostgreSQL features is that it can run dynamic websites and web applications as an alternative for it’s LAMP stack.
It can support JSON data.
Postgres isn’t owned by a single organization. It has therefore struggled to get its name known despite its full-featured and comparable with other DBMS systems.
PostgreSQL is extensively used for the Financial Industry, Government GIS data, Manufacturing, Web technology and NoSQL and also for Scientific Data collection .
