PostgreSQL is an innovative relational database administration system, which can be used on many platforms (UNIX, Linux, FreeBSD, OpenSolaris, Windows) and with a number of scripting languages (Perl, PHP, Python, Java, Ruby). Due to the fact that it is open-source, it may be effortlessly modified to match the demands of any developer who works with it. PostgreSQL is also amongst the the most trusted and stable database systems, with far better performance in handling sophisticated operations compared with similar systems. It is well suited for large-scale applications because a single PostgreSQL database doesn't have a limit for the size, while a single table can be up to 32 Gigabytes. It isn't a surprise that lots of business, academic and governmental entities are already working with PostgreSQL - Skype, the University of California, Berkeley and the US Department of Labor being a few examples.
