I think Dave fixed one of the cases that caused this a few revs ago, but
another one still remains. Steps to reproduce:
In pgAdmin 1.4.2:
* connect to a configured DB running on a networked machine
* open query
* issue a query
* observe result set
* disconnect your network connection (plug out and back in your cable,
e.g.)
* issue the query again
* get meaningful error message:
server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
In pgAdmin 1.6 RC1 (5574M):
* repeat the exact same steps as above
* get message ":" (just a colon) in the message window
