You would need a more extensive implementation of row level locks than 
PostgreSQL currently offers. There have been discussions about this in the 
past, but afaik no one is actively working on it.  You can probably find more 
info in the archives about it, also I believe it is on the TODO list, so you 
might find some more detail by looking there.
