PostgreSQL is an advanced relational database administration system, that you can use on numerous platforms (UNIX, Linux, FreeBSD, OpenSolaris, Windows) and with many different scripting languages (Perl, PHP, Python, Java, Ruby). Because it is open-source, it could be effortlessly modified to fit the demands of any developer who employs it. PostgreSQL is also among the most dependable and stable database systems, with significantly better efficiency in managing sophisticated procedures compared to similar systems. It is well suited for large-scale apps as a single PostgreSQL database does not have a limit for the size, while an individual table can be up to 32 Gigabytes. It isn't surprising that a number 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.
