WordPress is primarily designed to work with the MySQL database management system. However, it is possible to use WordPress with other database systems, including PostgreSQL, although it requires some customization and is less common.
Database Compatibility
WordPress uses MySQL-specific SQL queries, so using it with PostgreSQL requires modifications to make these queries compatible with PostgreSQL. This typically involves rewriting queries in the WordPress core, themes, and plugins.
- Database Driver: WordPress needs a database driver that can communicate with PostgreSQL. This can be achieved by using a custom database driver like
pgsqlorpdo_pgsql.
- Database Setup: During the WordPress installation process, you need to specify PostgreSQL database connection details, including the database name, username, and password, instead of the default MySQL settings.
Plugin and Theme Compatibility
Not all plugins and themes are compatible with PostgreSQL. You may encounter compatibility issues, and some features may not work as expected. Choose plugins and themes that explicitly support PostgreSQL or be prepared for customization.
- Testing and Debugging: After setting up WordPress with PostgreSQL, rigorous testing is crucial. You should thoroughly test your website’s functionality, as well as conduct performance testing to ensure it works well with PostgreSQL.
- Maintenance: Regularly maintain and update your WordPress installation and database. Be aware that future WP updates may require additional adjustments to maintain compatibility with PostgreSQL.

Community Support
While WordPress has a vast community and extensive documentation for MySQL, support and resources for WordPress with PostgreSQL are more limited. You may need to rely on your own expertise or hire a developer with experience in this specific configuration.
Performance Considerations
PostgreSQL is known for its robustness and suitability for complex data models. However, its performance may differ from MySQL in certain scenarios, so you should monitor and optimize your database accordingly.

To Sum Up
While it is possible to use WordPress with PostgreSQL, it requires additional effort, customization, and ongoing maintenance compared to the standard MySQL configuration. Unless you have a specific need for PostgreSQL or experience with it, sticking with the default MySQL setup is generally recommended for a smoother experience.
