PostgreSQL is an innovative relational database control system, that you can use on numerous platforms (UNIX, Linux, FreeBSD, OpenSolaris, Windows) and with various scripting languages (Perl, PHP, Python, Java, Ruby). Since it is open-source, it may be effortlessly modified to fit the requirements of any developer who works with it. PostgreSQL is also among the most efficient and secure database systems, with far better performance in handling complicated operations in comparison with similar systems. It's ideal for large-scale apps since a single PostgreSQL database doesn't have a limit for the size, while an individual table may be up to 32 GB. It isn't surprising that a number of business, academic and government entities are already employing PostgreSQL - Skype, the University of California, Berkeley and the US Department of Labor being just a couple of examples.
