PostgreSQL for Mac is a collection of graphical tools for using and managing PostgreSQL servers, as well as the server itself installable on any Mac running OS X version 10.4.x. It should work on 10.3.9, but it is not officially supported in the configuration.
Also included as part of the package is the pgCocoaDB framework, an open source framework for developers to leverage the power of PostgreSQL in their own applications.
