Top Reasons to Consider PostgreSQL

  • by

There are numerous databases that use relational management (RDBMSs) to select from, depending on which model best fits your data. PostgreSQL is among the most well-known and highly regarded open-source relational databases around the world.

This article will discuss some of the main reasons why many developers opt for PostgreSQL for their data management requirements. This includes everything from availability of features and standards compliance , to communities support, as well as administration.

Robust feature set

One of the main reasons to select PostgreSQL is its extensive array of options. PostgreSQL has an impressive array of functions related to performance security, security, programming extensions and configuration, among others.

A few of the features PostgreSQL provides include:

Support to write database functions:
Support for a variety of data types like:
Common database primitives such as numeric strings, boolean, and datetime types are used in the majority of databases and are supported in PostgreSQL.
address for networks: PostgreSQL supports various network-related types , such as CIDR addresses as well as subnet masks for addresses and MAC addresses both for IPv4 as well as IPv6.
Geometric types: A wide range of geometric types are available to help create two-dimensional objects. These include lines, points and segments as well as shapes that are complete such as polygons, boxes, and circles.
Money types: PostgreSQL’s money type stores currencies at precise fractional precision fixed. It is a type that is locale-aware and has automatic formatting of output.
ranges: Ranges enable users to work with natively the range of values dates and time ranges to schedule.
JSONB PostgreSQL’s native support to store and operate on JSON objects allows you to use both non-relational and relational data on the same application.
Hstore: This type lets you use key-value pairs directly.
arrays that are multidimensional: Arrays can be extremely useful to store values with multiple parts that aren’t much of a value beyond their context.
The ability to create your own complicated types: defining your own types can help you better align your database to the way that your data is displayed within your applications.
Full-text Search: Full-text search provides you with powerful methods to locate and operate on data that is semi- or unstructured text. Search can be refined to ensure relevance and matching.
Secure authentication, access control and access control systems that are suitable for businesses that are of any dimension: PostgreSQL has mature user authorization and authentication capabilities to determine who is able to use the system, and what information each user is permitted to view or perform.
Foreign data wrappers Foreign data wrappers allow to create tables and to access tables and data on remote servers.
Views and materialized views Views and materialized views allows for easy access to data through abstracting the table structure to provide information that is often requested together.
Comments on objects in databases The ability to include comments on databases, tables columns, tables, as well as other database objects lets you record decisions or details of implementation.
Write-Ahead Logging for point-in time recovery as well as failover and streaming replication. These techniques make sure that the database stays constant even when the software is damaged, and help to copy data between different systems to increase the capacity and back up your data.
Support for behavior similar to NoSQL such as the ability to store documents using JSONB or key value pairs with hstore: Being in a position to work with different database paradigms within one system can help to reduce administrative costs and increase compatibility between various representations.

Object-oriented database features

One of the primary ways in which PostgreSQL is distinct from other relational databases is its fundamental design.

Most relational databases are defined in terms of Relational Database Management Systems (RDBMSs). RDBMSs are specifically designed software to work with relational databases which are where data is stored in table-like forms with predefined columns and types. Data can be accessed or modified and then obtained using methods that are that are based on relational algebra generally using the structured query language (SQL).

PostgreSQL On contrary can be described as the same as an Object-Relational Database Management System (ORDBMS). This means it is able to perform the same functions as an RDBMS however it offers some features that are object-oriented.

Practically this implies that PostgreSQL lets you:

Make your own complicated data types
Overload functions that use different arguments data types
Define the inheritance relationships between tables

These tools are extremely powerful that allow you to manage your databases and data by using similar techniques you’ve used when writing programs. The more flexible approach lets you create different types of connections within your database rather than externally in your applications. This will help ensure uniformity and make sure that the behavior you want to enforce is more closely in relation to actual information.

SQL standards conformity

Another aspect where the PostgreSQL GUI is distinct from other database systems that use relational databases is its compliance with SQL standards.

SQL standards were developed in collaboration with ANSI as well as ISO groups with the aim of defining the minimum functionality and interoperability specifications to SQL implementations. Although the specifications offered by these bodies are designed to outline the features SQL systems should offer due to the complexity and the long-term development of the language strict conformity isn’t always feasible. As per the PostgreSQL document, there is no database that currently meets the requirements set out in the specification.

In light of that, PostgreSQL satisfies more of the SQL specifications than the other options. According to their own calculations they meet at least 160 of the 179 essential specifications set out by SQL:2016.

ACID compliance

ACID is an abbreviation in computer science. It refers to atomicity and coherence isolation, durability, and atomicity. These are the fundamental guarantees that transactions in databases must provide to prevent validity issues and ensure data integrity.

ACID compliance is the primary issue for relational databases since it reflects the standard expectations for the storage and modification of extremely structured information. Non-relational databases usually try to adhere to their own standards. This is usually symbolized by the BASE in the form of generally accessible, soft state and ultimately, the sameness.

While most database systems strive to offer ACID conformance, PostgreSQL has boasted ACID-compliance in its engine since. Because PostgreSQL is on a single engine for database, it implies the transactions that are ACID conforming by default. These guarantees are not based on locking the database using the multiversion concurrency controller (MVCC). For contrast, MySQL only supports full ACID compliance when you use the InnoDB or NDB databases. This could result in unexpected corruption when other engines are employed.

Community and open-source development

PostgreSQL is an open-source software project run by the PostgreSQL Global Development Group. It is licensed with The PostgreSQL License, a license that is recognized as valid by The Open Source Initiative.

There are numerous free relational databases available, PostgreSQL is developed and maintained without the involvement of a corporate owner or commercial counterpart. It allows contributors to determine its own route and focus on features that the community is concerned regarding the greatest. Professional services related to PostgreSQL are offered by businesses that frequently contribute to the project, but don’t manage the development process.

This emphasis on community-driven development has brought about a significant participation by PostgreSQL’s customers. Many top-quality extensions and apps can be found to enhance the capabilities of the base PostgreSQL software. Software developed by community members will help you manage the administration of your PostgreSQL servers, build information for your business, handle new kinds of data and also work with PostgreSQL with a variety of programming platforms and languages.


PostgreSQL has built a solid reputation for being a robust and feature-rich option for data that is relational. It is a reliable, stable and standard conformance, PostgreSQL checks all of the boxes needed for a variety of projects. In addition, if you need flexibility in the way you display data and be able to utilize various programs and programming languages, PostgreSQL is also a suitable option.

PostgreSQL is known for its outstanding implementation of key functions of relational databases without restricting it to the limitations of the traditional RDBMSs. Although no database is able to meet every requirement, PostgreSQL is an excellent alternative that can be adapted to meet the needs of a variety of applications.
