Our website provided a free download of PostgreSQLX 0.3 for Mac. This free Mac application is an intellectual property of Bruno Gaufier. The program relates to System Tools.
From the developer:
This program may be used to setup and customize a PostgreSQL server : Just drop PostgreSQLX.app in your application folder, launch it, and customize your server(s). 3 versions are available : An application with an embedded server : There is no need to download or install anything because the last version of the server (PostgreSQL 7.4.3) is already embedded within PostgreSQLX.app.
You may want to check out more software for Mac, such as InsomniaT or IBM Performance Analysis Suite, which might be similar to PostgreSQLX.
