pgAdmin III is a comprehensive PostgreSQL database design and management system for Unix and Windows systems. It is freely available under the terms of the The PostgreSQL Licence and may be redistributed provided the terms of the licence are adhered to. The project is managed by the The pgAdmin Development Team.

This software was written as a successor to the original pgAdmin and pgAdmin II products, which though popular, had limitations in the design that prevented them being taken to the ‘next level’. pgAdmin III is written in C++ and uses the excellent wxWidgets (formerly wxWindows) cross platform toolkit. Connection to PostgreSQL is made using the native libpq library.
