PostgreSQL is an innovative relational database control system, that you can use on many platforms (UNIX, Linux, FreeBSD, OpenSolaris, Windows) and with a variety of scripting languages (Perl, PHP, Python, Java, Ruby). Due to the fact that it is open-source, it may be easily modified to fit the demands of any developer who employs it. PostgreSQL is also amongst the the most efficient and stable database systems, with superior functionality in handling sophisticated operations compared to similar systems. It's appropriate for large-scale applications since a single PostgreSQL database doesn't have a limit for the size, while one table may be up to 32 Gigabytes. It's not surprising that a lot of business, academic and government entities are already working with PostgreSQL - Skype, the University of California, Berkeley and the US Department of Labor being just a couple of examples.
