If you decide to use a PostgreSQL-driven script application on any of your websites, you should have ample database storage space for it, in order to ensure that even when your website gets larger, it will work effectively and without any interruptions. Putting more items to an e-store or additional comments to a discussion forum are only two samples of what may expand your databases. Should you run out of space at some point, the functionality will decrease or the website might not be reachable at all owing to the fact that if the storage limit is reached, the script will not be able to store fresh content inside the database - user-generated or system one. Considering that PostgreSQL is designed for scalable web apps, it's likely that if you employ this type of database for your site, you will need additional space for it as your website expands.
