PostgreSQL is a high level relational database control system, which can be used on numerous platforms (UNIX, Linux, FreeBSD, OpenSolaris, Windows) and with many scripting languages (Perl, PHP, Python, Java, Ruby). Because it is open-source, it can be easily modified to suit the demands of any developer who works with it. PostgreSQL is also amongst the the most trusted and secure database systems, with significantly better performance in managing complex procedures compared with similar systems. It is suitable for large-scale apps since a single PostgreSQL database doesn't have a limit for the size, while an individual table can be up to 32 GB. It's not a surprise that a number of business, academic and government organizations are already using PostgreSQL - Skype, the University of California, Berkeley and the US Department of Labor being just a few examples.
