From Advenio Software:
Advenio SQLGrinder is a native Mac OS X SQL editor and developer tool. Using SQLGrinder you can create, edit and execute SQL queries. You can browse your database schema. Using SQLGrinder, you can easily connect to any database that has a JDBC driver. Because SQLGrinder is built using Apple's Cocoa framework, it looks and feels like a Macintosh OS X application, not like an application made on another platform and ported to OS X as an afterthought. SQLGrinder comes bundled with drivers for FrontBase™ from FrontBase Inc. and OpenBase SQL from OpenBase International, Ltd., as well as drivers for MySQL and PostgreSQL. SQLGrinder also makes it easy to connect to other databases such as Oracle 8i, Sybase and Microsoft SQL Server by simply dropping JDBC drivers into a folder.
