Thank you very much for sharing this "nohup" command.  That's really
helpful.

You putty to the server and run psql from a shell on the database
server?
 
If so, try putting the word "nohup" in front of "psql" -- that tells
the program to keep running even if the connection is lost.  (It is
short for "no hangup", I believe.)
 
On the other questions, I suspect that you'd be OK to delete the
partial database, as long as it doesn't show up in pg_database.  A
command which doesn't run to completion is always *supposed* to
leave the database cluster in a good state.  It never hurts to make
sure you've got a good backup before trying anything unusual,
however.
