PostgreSQL is an innovative relational database control system, which you can use on a number of platforms (UNIX, Linux, FreeBSD, OpenSolaris, Windows) and with many scripting languages (Perl, PHP, Python, Java, Ruby). Because it is open-source, it could be easily modified to fit the needs of any developer who works with it. PostgreSQL is also among the most dependable and secure database systems, with a lot better functionality in handling complex operations in comparison with similar systems. It is suitable for large-scale applications due to the fact that a single PostgreSQL database doesn't have a limit for the size, while one table may be up to 32 GB. It's not a surprise that a lot of business, academic and government organizations are already working with PostgreSQL - Skype, the University of California, Berkeley and the US Department of Labor being only a couple of examples.
