PostgreSQL is an innovative relational database administration system, which you can use on many platforms (UNIX, Linux, FreeBSD, OpenSolaris, Windows) and with a variety of scripting languages (Perl, PHP, Python, Java, Ruby). As it's open-source, it could be effortlessly modified to fit the demands of any developer who employs it. PostgreSQL is also among the most reliable and stable database systems, with significantly better efficiency in managing sophisticated procedures in comparison with similar systems. It is suitable for large-scale apps due to the fact that a single PostgreSQL database doesn't have a limit for the size, while a single table could be up to 32 Gigabytes. It isn't a surprise that many business, educational and government entities are already working with PostgreSQL - Skype, the University of California, Berkeley and the US Department of Labor being a few examples.
