For the Postgres provider, appending records to the data model and
updating records in the data model, will result in updating the data in
the database. A requirement is that at least one of your columns is a
unique index/key. At the moment I am working on getting remove to work.
Hopefully I can post that patch today.

An example of how I use update in my code:

 gda_data_model_begin_update(dm);
 retStatus = gda_data_model_update_row(dm, dmRow);
 if (retStatus == FALSE)
 {
                gda_data_model_cancel_update(dm);
                return 70020;
 }
 gda_data_model_commit_update(dm);


Hope this helps.

In the 1.2 branch it is called gda_data_model_end
