People at our topography lab, suggested me to use two different programs, one for working with the vectorial files of the database, and the other for scripting any interaction with it.

There are nice ports for OSX for both of them. As in many cases the installation will be more than few clicks but still is a small price to pay!
As a side note: the GRASS porting was developed in Italy, which makes me proud!
