PostgreSQL is an open-source object-relational database management system (DBMS) oriented at managing complex data structures and handling large volumes of data.
Since PostgreSQL requires a larger amount of system resources and memory, as well as specific configurations and permissions that are not available on our Web and Cloud hosting plans, the alternative is a virtual private server (VPS).
So make sure to select any of our VPS plans to start using PostgreSQL!
If you have a Web or Cloud hosting plan and require PostgreSQL, you can purchase a VPS plan and migrate manually by following this tutorial: How to Migrate a Website From Shared Hosting to VPS.
