Currently it is not possible to edit GRASS vectors with geometry stored in PostGIS.
You cannot use data which are under construction in mapserver, IMHO.
What kind of data, how often do you need to update the version in mapserver?
Data are edited by one or more users at the same time?

Yes, no easy solution.

No, shapefiles cannot be edited, the same problem - SFS as PosGIS.
Why native format and v.out.ogr is a problem?
