Those who only occasionally work with PostgreSQL, so to speak, want to use it as a desktop database: PostgreSQLX is a compilation of the PostgreSQL server that can be easily started and stopped as a Mac application. Ideal for developers. Then also the PGAccess interface and you can do without something like Microsoft Access. Of course, all of this only from 10.3 (it's about time 10.4 comes out and I'm up to date at home again).
