In case you decide to employ a PostgreSQL-driven script app on one of your websites, you need adequate database storage for it, so as to guarantee that even if your site expands, it'll function effectively and without interruptions. Adding extra items to an electronic store or additional comments to a message board are just two examples of what may increase the size of your databases. In the event you run out of storage space at some time, the overall performance could decrease or the website may not be available at all owing to the fact that if the storage space restriction is reached, the script will not be able to keep fresh content inside the database - user-generated or system one. Since PostgreSQL is intended for scalable web apps, it's more than likely that when you use such a database for your website, you will need more space for it as your site grows.
