This ticket was open after the observations made here
use the "regions" layer you can find in the spatialite sample dataset: you can save it as shapefile and import to postgis. Tested also with other layers, like the "world borders" vector.
In qgis trunk (but not in 1.3) after merging non adjacent or non overlapping features (or features with islands) of a postgis layer, after toggling editing to save changes, the program returns
"ERROR: duplicate key value violates unique constraint "regions_pkey""
and after that
"Could not commit changes to layer regions
Errors: ERROR: 1 feature(s) not added.
SUCCESS: 2 feature(s) deleted."
If the same is done on a spatialite layer only the latter message is shown (again, only in trunk, not in 1.3).
