When you use a script-driven application on your site and all content that you make is stored in a database, your website hosting plan should include an adequate amount of database storage, so that you can make certain that even if your website grows, you won't experience any type of problems as a consequence of the lack of storage space. PostgreSQL is an example of a popular database control system that's used with a large number of scalable web apps and if you need top-notch performance and reliability for your website, it is very likely that you'll take advantage of this system. With this in mind, you'll need a web hosting package that will not restrict your web presence, especially if you would like to manage multiple websites and each of them employs PostgreSQL databases.
