PGnJ is a freeware, java database manager from Sliced Software
Originally downloaded 4/23/06. There is no shortage of freeware database management tools for Mac OS X, but this is a new one on me. If the clean interface of the author’s website says anything about how he thinks about application interfaces, it might have some good new ideas.
Update 10/18/06. PGnJ is a good start, but doesn’t feel finished to me. For the gory details on my review of Mac OS X database management tools for MySQL, see my October 2006 article on the subject, including specific findings about PGnj.
