pgAdmin is a free software project released under the PostgreSQL/Artistic licence. The software is available in source and binary format from the PostgreSQL mirror network. Because compiling from source requires technical knowledge, we recommend installing binary packages whenever possible. pgAdmin is the most popular and feature rich Open Source administration and development platform for PostgreSQL, the most advanced Open Source database in the world. pgAdmin is a management tool for PostgreSQL and derivative relational databases such as EnterpriseDB's EDB Advanced Server. It may be run either as a web or desktop application. As pgAdmin is a web application, it can only interact with the local filesystem in ways that are allowed by modern web browsers. This limits what is possible for security; essentially files can only be "downloaded" or "uploaded" (through a form).
