Druware has released a Mac OS X installer with additional tools for PostgreSQL 8.01. The developer’s web site did not have the latest build – however – you can grab it at Version Tracker.
Similar to what Marc Liyanage has done with MySQL, PHP and other tools for the Mac, Druware makes PostgreSQL accessible to the platform. This is done in part by installing into the Panther hierarchy, allowing users to view database logs in the console.app and providing a GUI interface. Druware hopes to evolve the GUI over time in Microsoft Management Console style (think MS SQL Server GUI).
