Manifold/PostGIS data manipulation and export

Question

I'm currently working on a GIS database project using Manifold Ultimate. I am able to import data from PostGIS via the database console, and edit the data as a table object within Manifold.

1. How do i 'commit' these changes back to PostGIS?
2. I am required to submit the exported database. What format is expected for a PostGIS export and how is the exporting done?
