PostgreSQL Features Various Advanced Features of PostgreSQL
The above items and other new features of PostgreSQL 16 are explained in more detail in the sections below. The following section will talk about the recommended practices for your WordPress database. Apart from being a reliable and solid database platform, it is fairly easy to master. The learning curve isn’t as steep as some of its contemporaries since you don’t need to have a complete grasp of SQL to start working with MySQL.
PostgreSQL is an open-source and feature-rich ORDBMS database that competes with real-time, top-ranked databases such as Oracle. PostgreSQL makes setting up and using databases easier and simpler both on-premises or in the cloud. In an environment with a large number of databases on a private or public cloud, automating the building of PostgreSQL instances can save a lot of time. It is also being widely adopted across all platforms, including Docker containers.
PostgreSQL offers more advanced functions, like handling complex queries and advanced data types, while MySQL offers fewer features on advanced functionalities and data types. Thus, setting up and managing MySQL databases is simpler than PostgreSQL. On the other hand, PostgreSQL is ideal for large data sets and large numbers of users when you need feature-rich database management. PostgreSQL is highly extensible as its operation is catalog-driven, i.e. information is stored in databases, columns, tables, etc. PostgreSQL not only holds an increased amount of information in its catalogs but also details on the data types, access methods, functions, and so on.
MySQL also supports SSL-based connections over the network and provides security based on SE-Linux modules. Integration with external authentication systems, such as LDAP and PAM, is part of the MySQL enterprise edition. MySQL grants access to the database, objects, and connections via ROLES and PRIVILEGES. Every user must be granted a connection privilege using an SQL for every IP address from which a user is connecting, or connections can be granted all at once to multiple IP addresses as part of a subnet.
What is PostgreSQL: Data analyst use cases
Some of the features are widely appreciated as they are incredibly useful. The following section contains some of the well-known features of PostgreSQL that you should look at, as they will help you improve performance in production and make operations easier. Since most applications will not need the fastest or most powerful database performance, this may not be a concern. But if optimal performance is a factor, you might want to consider other databases such as MySQL or NoSQL databases instead.
If there is a table in your database that does not relate to any other table, a primary key is not needed. Otherwise, it is better to use it in order to eliminate duplication of data, reconcile it, and speed up its processing. In this post, we walk through an example for creating an active-active replication setup between two RDS for PostgreSQL instances. We also show how to monitor replication lag between instances, and review how to detect and resolve conflicts.
Comprehensive monitoring features
(e.g., [4,9) represents all integers starting from and including 4 up to but not including 9.) Range types are also compatible with existing operators used to check for overlap, containment, right of etc. A search_path setting determines the order in which PostgreSQL checks schemas for unqualified objects (those without a prefixed schema). By default, it is set to $user, public ($user refers to the currently connected database user). This default can be set on a database or role level, but as it is a session parameter, it can be freely changed (even multiple times) during a client session, affecting that session only. PostgreSQL includes built-in binary replication based on shipping the changes (write-ahead logs (WAL)) to replica nodes asynchronously, with the ability to run read-only queries against these replicated nodes. This allows splitting read traffic among multiple nodes efficiently.
- PostgreSQL is highly scalable — in the number of concurrent users, it can accommodate as well as the quantity of data it can manage.
- Previously in this article, we have been using dbForge Studio for PostgreSQL to provide you with visual examples of how to deal with the primary keys.
- Today, we’ve taken a look at how it can meet the needs of both small projects, as well as large and complex enterprise use cases.
- PostgreSQL has transaction support, full-text search and constraints like a foreign key.
- Other plugins can be leveraged to backup your database before making changes, for instance, during a migration.
- Professional services for PostgreSQL are provided by companies that often contribute to the project but do not control the development process.
The increased flexibility lets you model different types and relationships within the database system instead of externally within your programs. This can help maintain consistency and enforce intended behavior closer to the actual data. “As relational database patterns evolve, PostgreSQL continues to make
performance gains in searching and managing data at scale,” said Dave Page, a
PostgreSQL Core Team member. “PostgreSQL 16 gives users more methods to scale-up
and scale-out their workloads, while giving them new ways to gain insights and
optimize how they manage their data.” PostgreSQL 16 also introduces improvements in shared buffer usage, ensuring efficient memory management.

Some areas have even witnessed performance boosts of a staggering 300%. Let’s dive deeper into some of these PostgreSQL 16 features – especially the logical replication enhancements, as they represent opportunities for businesses to optimize their data management strategies. MariaDB is a commercially supported fork of the MySQL Relational Database Management System that boasts a fundamentally distinct approach to meeting the needs of the modern world. MariaDB’s purpose-built and pluggable storage engine offer support for workloads that previously needed a vast array of specialized databases.
If there is an import issue, it will throw an error and stop the import immediately. The following sections will cover some of the most common applications of PostgreSQL in the modern world. To fulfill this objective, difference between postgresql and mongodb it is fair to set the value of the shared buffer as 25% of the total memory if we have a dedicated server for PostgreSQL. The default value of the shared buffers from version 9.3 onwards is 128 MB.
PostgreSQL vs. MySQL
The useful support of JSON also makes PostgreSQL an excellent database solution for scaling NoSQL workloads. Deploy your web projects to high-performance, ready-to-go cloud hosting in 3 steps. Not only do WordPress errors hamper the proper functioning of your website, but they can have a detrimental effect on the consumer experience.
Other plugins can be leveraged to backup your database before making changes, for instance, during a migration. Apart from improving your website speed, you can use database plugins to provide a more efficient user experience while improving your chances of ranking higher on search engines. Many startups and large enterprises use PostgreSQL as the main data storage solution for products, solutions, and internet-scale applications. Supply chain performance can be optimized by using this open-source DBMS as a storage backend. As a result, this allows companies to reduce the operation cost of their business.
It is a terminal-based front-end command-line tool; where we can directly enter the SQL queries or run them from a file and we can also see the query results. It offers us many Meta commands and several shells, such as automate extensive ranges of tasks and facilitate writing the scripts. We therefore

other table in the database relates to the collections table by the
collection Name. We are thrilled to announce the release of our latest products, DBConvert / DBSync for DBF and PostgreSQL. These powerful solutions are designed to streamline your data conversion, migration, and synchronization processes between DBF and PostgreSQL databases.
